[BUG] Padding/border around fullscreen Electron on Wayland window with WaylandWindowDecorations enabled

[SilverMight]

Describe the bug
Electron windows running on Wayland (--ozone-platform-hint=wayland) with the WaylandWindowDecorations feature enabled (--enable-features=WaylandWindowDecorations) have a border around them, even after the CSD fixes in Electron (electron/electron#34955). Problem does not occur on other themes. Tested on GNOME 42/43.

To Reproduce
Steps to reproduce the behavior:

1. Launch any electron post-CSD fixes with the Dracula GTK theme.
2. Try to fullscreen it and see that there is a border around the window.

Expected behavior
Properly fullscreened Window, no borders.

Screenshots

I have the same issue. Has there been any progress on this?

If there's anyone with an idea on how to start, I can try to figure out a fix, but I'm not at all familiar with how gnome works under the hood.
