Allow `CopyQ` to be used if the browser loses focus during some renaming operations

Describe the bug

To Reproduce

1. Create or open your imdb list (page like https://www.imdb.com/list/ls…/edit/).
2. Add something to it.
3. Click "Add a note."
4. Activate the CopyQ paste dialog.
5. The input field will lose focus, editing mode will end, and the message "List item description was successfully updated" will appear.

This is exactly how Windows Clipboard Manager behaves.
