Can we share some of this with DisableMinMaxConstrainsScope?

No without making them unnecessarily complex because there are some usages of ScopedUnboundedBox that do not imply DisableMinMaxConstrainScope

Oh wait I thought you're talking about the overriding scope. Now that you mention I think I have messed it up and reported two bugs for the same issue...

I'll mark bug 226634 as duplicate. Sorry for the mess

I've a new patch for this issue that does not suffer from the Gmail bug. It's based on the previous work done in bug 230755 so I need to get that in before posting a new patch here (which BTW fixes 3 tests with no regressions).

r=me, let's hope there's no more unexpected breakage.

Nit: We've the very same if just below, maybe we can put this inside that if directly.

Nit: I've the feeling that m_originalSize, m_originalMinSize and m_originalMaxSize might be easier to understand.

Thanks for the review!

Sure, I developed both patches independently so came up with two different presentations. I'll move them there.

Makes sense. I'll rename before landing
