This was an oversight by me when writing the line wrapping code.

When set() gets called when coming back from the editor, InputArea already has a height set, so it won't try to recalculate.

Another option would be to invalidate the height (self.height = None) instead of recalculating in set(). @osa1 which do you prefer?

Great catch @trevarj, thanks!

I think I prefer self.height = None and delaying calculating height as much as possible. Reason: if there are other code that also invalidates the height after editor returns, but before the next draw call (e.g. maybe we decide to fall back to scrolling) we avoid redundantly calculating height here only to invalidate it again before the next draw call.

Changed to self.height = None, and squashed my commits.

Thanks!
