[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 (https://github.com/electron/electron/pull/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.
