Since you cannot play WoW without staging patches it is kinda hard to say this is only a staging bug.
Yes, that's accounted for in the link above.
It is ofc possible to pick those patches that are not just "rebases" when viewing https://github.com/wine-staging/wine-staging/commits/master
If however a wine upstream patch causes a bug, but you MUST use staging to play a game, it is a tedious task to bisect ALL patches from 4.14-4.15 as this is many hundreds and taking quite a few minutes between each compile.. Well..
The magic of bisections is that "many hundreds" still only means about ten steps ;-)
Anyway, yes, it's a lot of work, but someone has to do it, or you have to ask developers to solve this bug as if they knew nothing about it. Believe me when I say that's far more difficult.
