--- Comment #2 from Gijs Vermeulen  ---
The message is gone now, so I don't know if that is enough?

Just as an aside:

How does one know if these are "really" fixed? In the case of 'tan' (bug 54377)
it seemed like it was fixed because the message was gone and 'tan' was at least
being parsed, but it wasn't really fixed.

Can that be the case for this bug and bug 55453 as well for example?
