terminal does not resize correctly after maximise by sliding to top panel

[Colin Law]

On up to date Raring. To replicate
Open gnome terminal
Slide title bar to top panel to maximise window
Slide away from top panel to restore it
It should return to original size, but instead it remains near maximised size.

If instead the terminal is maximised using the window control then it correctly restores the size (whichever method is used to restore the window).

Status changed to 'Confirmed' because the bug affects multiple users.

Also observed in 13.04 when using keyboard commands to maximize and restore. Upon restore, the window occupies nearly the full desktop.

[Matthew Fearnley (matthew-w-fearnley)]

This is still a problem in 16.04. The terminal will become a desktop-sized window after restoring, after every way I can think of to maximise (snapping to top, double-clicking the title bar, double-pressing F11).

If the window was partly offscreen when it was maximised, it still expands to desktop size on restore, but the top-left corner is restored to its original position.

Not so much still a problem as an old problem returned. It was not present in 14.04 to 15.10 (at least for me) but has returned with 16.04.

[Matthew Fearnley (matthew-w-fearnley)]

Yes, I have just tried 14.04 quickly, and it is restoring OK there. I notice that since then they've added the ability for text to re-wrap on terminal resize. I don't know if that's related.

[Matthew Fearnley (matthew-w-fearnley)]

Note: on watching the behaviour more closely: on restore the terminal window is very briefly restored to its correct size/position, then almost immediately changes its size to fill the screen.

It also jumps to the top-left corner at the same time, I think if and only if it was entirely onscreen.
