Is there a find item synergy?

In classic Diablo 2, do you get the find item synergy effect when skill investing in find potion?

Looking at the contents of the D2R patch, there was a synergy between the find item skill and the find potion skill from the beginning.
It was not marked properly, but now it says that it has been corrected to be marked correctly in the tooltip.

I wonder if this applies to classic Diablo 2 as well?

No, they added the synergy in D2R, but they did not make changes to D2 Legacy
