Hey would you be kind as to record a short video of how the wall jump looks for you? When I test it I don't have the same problems.
Here you are, this should be viewable for a bit:

The small issue at like 7 seconds isn't the worst, I suppose you're reading facing direction to determine where to push the player. The real issue is the notch jump attempts starting around 14 (approach from say, 12..5). For me, persists on Firefox and DuckDuckGo browsers (Win10).
