[BG] Temporal Tempering Bug

Temporal Tempering description states “Your Tavern spells cast twice”, but cards with “When you cast a tavern spell, …” triggers only once.

For example, Saloon Dancer description states “When you cast a tavern spell, give another friendly minion +3/+3”, but it buffs a friendly minion only once.

Yes, because YOU only cast one spell.

The second copy is cast by a game effect, not by you.

Yes, I thought the same thing, but to me it looks more like an excuse for a bug than the developers’ intention. I think in this case the effect should work twice.
