Why should it be called? What are you trying to prevent?

I don't see how it's possible to call WaitFor* recursively.

[kolos1, 2017/08/08 12:37:16]

Yes, it is not possible to call a sequence of two Wait... functions.
It was a sort of additional check. Removed.

[vasilii, 2017/08/07 17:13:24]

I'm concerned that if there is a manual fallback currently and I call
WaitForSavePrompt then the function returns immediately. I think it doesn't
match the expectations of the caller.

This assertion is only needed so that the test crashes nicely if the current
state is wrong. If a test really cares which prompt is shown then it should
check it.
