miral-kiosk crashing specificity with a mir-kiosk-apps fancybrowser (or any webkit example)

It seems for unknown reasons in miral::WindowInfo::constrain_resize the ar.width == 0 (pretty sure due to default value). Is getting past the error bit which seems from my read can only happen is the new_size.width < 0. So its pretty much doing 0 - -width * max_uint which will get past the error check.

From the logs them selfs I dont see *any* crazy numbers that would cause the width to become negative.

A fix is up, and a test that confirms that negative width bit but unsure how it got to be in that state.
