Mechanic Bug: Double White Herb with Symbiosis (in Double Battles)

[SkyswordDev]

When both active Pokemon hold a White Herb while one Pokemon has Symbiosis, if the other Pokemon has one stat lowered, it will immediatly consume both White Herbs. (According to the chat log even before Symbiosis is triggered.)
Example: https://replay.pokemonshowdown.com/gen9doublesuu-2350818911-njnn3pcvmtvx35nioxky2x5hg5j2o58pw

Expected behavior:

1. non-Symbiosis Pokemon gets stat lowered
2. White Herb 1 gets consumed and clears the lowered stats
3. Symbiosis gets triggered and passes White Herb over
4. White Herb 2 is available for the non-Symbiosis Pokemon

This also happens when only a single stat gets lowered:

Mental Herb works as expected:
