Syntax can be changed in the Find input field

Open the Find pane (Ctrl+F/Cmd+F). Click on the syntax selector in the bottom right corner of the screen and select any syntax from the list. Bam, the Find input field is now treated as a full-blown buffer with its own line numbering and syntax!

This might be useful as a feature, but the way it works now it sure looks like a bug: the syntax indicator still shows the syntax of the file, the Find input field looks ugly, and there is no way to return it to normal.
