Using Ctrl-F makes the state of the vim mode inconsistent

[trubachoff]

After Ctrl-F plugin not working. GEdit ver 3.28.1

[JonLiuFYI]

The plugin does still work after pressing Ctrl+F, but the vim mode indicated in the status bar is out of sync with the current state of the editor.

Reproduce

1. Start in normal mode
2. Press Ctrl+F and search for anything
3. Press enter or escape to dismiss the find box
4. Press J

• Expected: move down one line, because the status bar says Vim Mode: NORMAL
• Actual result: you type a j into the file as if it were actually Vim Mode: INSERT

Once you're in this out of sync state, pressing Ctrl will silently return to the proper normal mode behaviour.
