Issue description

The find match highlight in script editor sometimes gets stuck visible even though the find panel has been closed. The find panel has to be reopened and closed to reset the highlight.

Steps to reproduce

Open two script files in the editor. Use CTRL+F to find something in one of them, so that it matches and highlights some text. Then switch to the other script while the find panel is open. Close the find panel and return to the first script.
