Fix Timer error on startup

[KoBeWi]

Fixes #87542 (comment)

[Mickeon]

It does fix the error, but it's a bit hacky, as before. It's also a bit inconsistent with the set_warning_count(0); below which may make this harder to follow. As I mentioned once, perhaps it's better to just bite the bullet and fetch the editor setting in the constructor...?

[KoBeWi]

Yeah that's an alternative.

Pushed a different fix.
