DO NOT MERGE Fix issue #3408542: "resizeable" attribute required to get out of compat mode

The "resizeable" attribute of supports-screens was never well documented,
so many apps don't set it.  Assuming that if they are explicitly saying
they support large or xlarge screens then they are also implying that they
are resizeable.
