Session timeout

Is there a way to set a session timeout.

I often have multiple windows open when I’m coding and one window is the editor.

I sometimes find on saving code changes it just sits there ‘spinning’ and never saves.

I have to refresh the page and this looses unsaved edits. It is as if a session timeout / disconnect has happened.

I can manually resolve by stopping the ‘looping’ save dialog, copy all code to clipboard, refresh window, repaste the clipboard contents over top of old code and then save but this is tedious.
