One of them is already getting attention so hopefully they will notice (you know how it is), the other one has literally only affected me as far as I can see and I haven't put together a minimal test case yet. It's a weird one!
Agreed, it would be nice to see the bug. AFAIK they take standards compliance pretty seriously. I'm sure someone would look at it, especially if Chrome is behaving differently from FF/IE9/Safari.
