Issue description

Trying to select the next ocurrence of anything in the code editor, while it's inside a collapsed function, returns an error:

I believe it should expand the function, then select the ocurrence.

Steps to reproduce

Select a word and press Ctrl + D to find and select the next ocurrence of it. A function must contain the word, and it must be collapsed.

This should be easy to fix after #86978 since it adds a _unhide_carets() method in TextEdit that can probably be used for this.
