fix: wait for window creation no matter if on main thread

Closes #10157
Closes #13046
Closes #14914
Closes #14915

Reference: #10157 (comment)

#14915 did this with the same approach, but the use of LLM made tons of noise, that it covered up what the change was really about...

For reviewer: I don't know if this was a mistake not to do this or there's a legitimate reason for that
