I've struggled to create a reduction for this and failed so far. If anyone can pitch in with one I will definitely take a look.
@wangxianzhu: Request you to please take a look into it as per the above comment.

Thanks.!
wangxianzhu@/ robhogan@ - could you please update on the issue, it was marked as RBS and tagged for M53.
I suspect we miss overflow update of the viewport when a dialog is closed.

Not a release blocker IMO.

Do you have a test case of the kind of thing you have in mind? (It doesn't have to repro the bug, I can prod it till it does.)
http://output.jsbin.com/vebakef/1 is a similar case, though it can't reproduce the issue.
