Bug#878943: mutter: 2.26 regression: one-dimensional window maximize no longer possible

[Zack Weinberg]

Package: mutter
Version: 3.26.1-5
Severity: normal

With the GNOME 2.26 mutter, one-dimensional window maximize no longer
works correctly.  Specifically, if you set one of the "titlebar actions"
in gnome-tweak-tool's "windows" tab to either "toggle maximize vertically"
or "toggle maximize horizontally", then triggering the action will
cause the window to be fully maximized instead of maximized in only the
desired direction.

I waited to file this bug until both the 2.26 gnome-shell and the
2.26 gnome-tweak-tool appeared in unstable, but the behavior has been
consistently wrong since 2.26 mutter appeared in unstable, so I'm
pretty sure it's mutter's fault.
