Comment 7 for bug 1186560

I have a fix for both this and bug 1186723 , but ...

I'm not a huge fan of the way things are working at the moment. I think we really need a proper testsuite around this functionality before we land any more fixes. A lot of the behavior around maximization and decoration is very very tightly coupled and fixing one thing often breaks another.

I'll post the fixes up for a test-only review, but I think we should hold any further work here until the acceptance test suite is delivered. I'll make that a top priority.
