WindowResizeObserver is leaked because it never unregister its resize DOM listener.
We never unregister it because don't call its super class Observable::destroy from here:
https://searchfox.org/mozilla-central/rev/13378066961f195595822d4f543c8ac5b7f46490/devtools/server/actors/reflow.js#501-504
And that's Observable::destroy which will ultimately lead to call _stopListeners...
Because of this we keep the target actor in memory.

We weren't calling super class destroy method (Observable::destroy),
which is the one which will force ultimately unregistering the resize DOM listener.
