1736209 - [wayland] Dragging window that was created maximized moves window origin to cursor location

Status: NEW

(Core :: Widget: Gtk, defect, P3)

Description

[Kestrel]

Attachment: drag-maximized.webm

STR:

1. Start with MOZ_ENABLE_WAYLAND=1 on Ubuntu 21.04.
2. Make sure the initial window is maximized, if not then maximize and restart or create a new window.
3. Drag maximized window titlebar down so it unmaximizes.

Expected:

Cursor grab location remains the same, window does not shift position relative to cursor.

Actual:

Window repositions so the cursor grab location is the top-left window corner. This makes the window move mostly off-screen when dragged from the right side. Only happens for windows that were created maximized.

Not a regression, reproducible going back to 2019.

Yes, I can reproduce it too.
