Metadata losing keyboard focus while typing

[DarrenCook]

I can often be typing in the Metadata tab (the Notes/References section is where I have noticed it most) and keyboard focus disappears.

I cannot reproduce this on demand (UPDATE: I can now, see first comment). I am often pasting in, then editing, text containing markdown. So it might be related to that. But I suspect it is likely triggered by the saving of the scene data.

This is usually just mildly irritating, but as I just commented on #1258, it seems the keyboard focus can get moved to the project tree, and the typing intended for the metadata window then can cause whole scenes to be deleted and lost forever.

I found the logs, and so have been running tail -f while using Manuskript.
I was about to propose it is correlated with the auto-save, but having done more tests I think I can get it to happen consistently by:

Cursor into summary. Then ctrl-v to paste. The caret flashes once then disappears. If I start moving the caret during that brief half-second window, then it stays there. Otherwise it appears reproducible!
And it happens in exactly the same with ctrl-x to cut.
But not for ctrl-c, so it seems the text has to change.

I can also get it to happen with highlight a few letters, press del, then ctrl-z. It happens even if it was a single character being restored by undo.

Yet it won't happen with normal typing.

Aha! I've just associated it with another bug I have been trying to narrow down enough to report.
In the main editor do one of the above triggers (paste/cut/undo). The caret doesn't disappear, but what happens instead is that contents of the Metadata section disappear and it greys out.

They don't come back until I make another edit in the main edit window. No data lost. I've also seen it run an auto-save during the blanked out phase with no problem.

Hhmmm, I can't get this to happen every time. There seems to be times when it is perfectly reproducible, though, especially with ctrl-z, like it has got into a situation (undo stack??) where the bug can be triggered.
