[Bug] Maximizing a sticky window and un-sticky-ing the same window can crash the compositor

[D-Brox]

Steps to reproduce:

1. Enable Sticky window in any window
2. Maximize that window
3. Disable Sticky window
4. The window size will be reset to the one before maximizing instead of maximized (expected behaviour)
5. The window is left in a state where moving or resizing will crash the compositor

I checked the syslog and this seems to be the root cause of the crash:

The code is reaching this unreacheable!() statement:

cosmic-comp/src/shell/workspace.rs

Line 649 in 7ac204e

ManagedLayer::Sticky => unreachable!(),

When the active window is in a state where it causes a crash it doesn't have an active window hint border since it's supposed to be maximized. Curiously, after taking this screenshot the window returned to the expected maximized size, but it still can crash the compositor when moving or resizing.
