Constant complaints about negative sizes

[scarlion1]

Describe the bug
When Unite is hiding the titlebars, journal is flooded with messages like the following from every app:

gnome-calculato[1209362]: GtkWindowControls 0x56351ed07b50 (windowcontrols) reported min width -92, but sizes must be >= 0

mutter-x11-fram[1206284]: GtkHeaderBar 0x560535d07300 (headerbar) reported min height -163, but sizes must be >= 0
mutter-x11-fram[1206284]: MetaFrameHeader 0x5605357d3750 (widget) reported min height -200, but sizes must be >= 0
mutter-x11-fram[1206284]: MetaFrameHeader 0x5605357d3750 reported baselines of minimum -178 and natural -178, but sizes of minimum 0 and natural 0. Baselines must be inside the widget size.

Hey @scarlion1, thanks for the report. The extension uses negative margin (css) to hide titlebars in CSD apps. Unfortunately there is no other way to achieve this. Leaving the issue open in case someone has a better solution that will not trigger the warnings.

Yeah I tried a number of alternate ideas too even with ChatGPT. It had some creative ideas like offsetting the negative margin with positive padding, and a slew of different selectors.  Nothing worked though in the end lol.  I guess it needs to happen at the server level, so in mutter somewhere?

In the mean time I guess I'll just redirect the mutter-x11-fram messages to another journal or something.

What about when an app has a full-screen mode?  The titlebar goes away.  Isn't there a way to tap into that functionality but without maximizing the window?
