Strings in context menus can go outside of button if they very long

[Vovkiv]

If line gets very long in context menus (in this case, menu for converting tags), it will be wrapped in way that it can go outside of button boundaries, so text might get overlapped:

This shouldn't be a problem in context menus. The path popup is a custom popup, so it's a fixed width.

I think the correct solution would be to let the text shrink a little, and if it's still not enough, make the popup wider.
