The Prophet Skeram in AQ40 is disabling all buffs and also all passives from talents/racials/glyphs upon activating the 2nd split phase at 50%. The first split phase at 75% worked fine.

Take a look at the following entries at 0:25 and 3:39:
00:25.597 The Prophet Skeram Earth Shock Corpsetwo 2202 (U: 2730, M: 528, 19.34%)
03:39.810 The Prophet Skeram Earth Shock Corpsetwo 893 (A: 1256) (U: 2664, M: 515, 19.33%)
The percentage at the end of the line refers to the percentage of damage mitigated. In my situation, this comes by multiplying all of the following effects:
Improved Righteous Fury : 94% damage taken
Blessing of Sanctuary : 97% damage taken
Guarded by the Light : 94% spell damage taken
Shield of the Templar : 97% damage taken
Glyph of Divine Plea : 97% damage taken
Multiplying 0.94 * 0.97 * 0.94 * 0.97 * 0.97 = 0.8064378628 spell damage taken, which is equivalent to 19.35621372% spell damage mitigation, which agrees with the combat log entries.
This is meant to prove that I have all of these passive effects on me early in the fight.

Ardent Defender procs on me at 1:24.300. Note that the debuff faded at 3:24.299, 2 minutes afterward.

Said Ardent Defender healed me for 8175 HP.

Here’s the Ardent Defender passive damage reduction in effect.

Here’s my buffs for the fight. Note that at 3:43.054 I lose the following buffs:
03:43.054 Corpsetwo’s Righteous Fury fades from Corpsetwo
03:43.054 Corpsetwo’s Retribution Aura fades from Corpsetwo
03:43.054 Corpsetwo’s Seal of Vengeance fades from Corpsetwo
03:43.054 Corpsetwo’s Greater Blessing of Sanctuary fades from Corpsetwo
03:43.054 Corpsetwo’s Divine Plea fades from Corpsetwo
03:43.054 Corpsetwo’s Sacred Shield fades from Corpsetwo
03:43.054 Corpsetwo’s Sacred Shield fades from Corpsetwo
03:43.054 Corpsetwo’s Libram of Obstruction fades from Corpsetwo
I did not hit a cancelaura macro or anything like that. I specifically disabled all of my addons for this boss attempt.

Here’s a list of the enemy casts for the fight. Note that the 2nd split occurs simultaneously with me losing all of my buffs.
01:09.287 The Prophet Skeram casts Summon Images (1st split)
03:43.054 The Prophet Skeram casts Summon Images (2nd split)
Recall the 19.35% spell mitigation from before. One combat log entry showed that at 3:39, I had the full suite of spell mitigation. Yet, at 3:45, the following line implies that I have exactly 0 spell damage mitigation:
03:45.077 The Prophet Skeram Earth Shock Corpsetwo 2126 (A: 500) (U: 2626)
While some of this can be attributed to the missing buffs above, some of the missing spell damage mitigation effects are 100% passive. Shield of the Templar talent reads as follows: “Reduces all damage taken by 3% and grants your Avenger’s Shield a 100% chance to silence your targets for 3 sec.” There is nothing conditional about that. The Guarded by the Light talent similarly has a purely passive damage reduction.
At 4:08 I die to one of the clones’ Earth Shocks:
04:08.981 Unknown Actor 3 Earth Shock Corpsetwo 2432 (O: 40) (U: 2548, M: 76, 2.98%)
Recall that my Ardent Defender activated at 1:24.300 and the associated debuff faded at 3:24.299. Here, I take a killing blow 44 seconds later, but Ardent Defender is nowhere to be found. It didn’t activate at all, even though there’s no reason for it to behave as such.
03:50.426 Corpsetwo gains Blessing of Sanctuary from Corpsetwo
I reapplied Blessing of Sanctuary at 3:50, which gave me 3% damage reduction.
03:51.159 Unknown Actor 3 Earth Shock Corpsetwo 2648 (U: 2730, M: 82, 3.00%)
At 3:51 it’s evident that the damage reduction took effect.
04:00.693 Corpsetwo gains Divine Plea from Corpsetwo
At 4:00 I re-applied Divine Plea, which should’ve activated the Glyph of Divine Plea for 3% extra damage reduction. However, this damage reduction didn’t take effect per the below:
04:04.115 Unknown Actor 3 Earth Shock Corpsetwo 2577 (U: 2656, M: 79, 2.97%)
After running back to the instance and rezzing, this screenshot was taken:

After taking the prior screenshot, I relogged. After relogging, this screenshot was taken:

Note the following discrepancies in my stat page and health bar:
Max Health : 27284 after rezzing, 29384 after relogging. Note that the Protection tree gives several stamina bonuses.
Crit Chance : 5.94% after rezzing, 15.94% after relogging. My spec gives 10% crit from talents: 3/3 Combat Expertise (6%), 2/5 Conviction (2%), 2/3 Sanctity of Battle (2%).
Expertise : 17 after rezzing, 26 after relogging. The Combat Expertise talent gives 6 expertise, and the Sword Specialization Human racial gives 3, for a total of 9.
Dodge : 16.09% after rezzing, 21.09% after relogging. The Anticipation talent gives 5%.
Parry : 13.94% after rezzing, 18.94% after relogging. The Deflection talent gives 5%.
Armor : 23032 after rezzing, 25180 after relogging. The Toughness talent gives 10% armor, although this only applies to the armor granted by items.
Power : 2140 after rezzing, 2428 after relogging. The Divine Strength talent gives 15% strength which converts into Attack Power.
As shown above, relogging restored all the proper passives to my character.
