fatal (debug-build) assertion with width:-moz-max-content in vertical writing mode
The patch for bug 1122366 means that in vertical writing mode, nsBlockFrame::IsSelfEmpty will be passing width coords (instead of height) to IsNonAutoNonZeroHeight(), and these may include things like -moz-max-content that it is not prepared to handle. This is similar to the assertion we had in bug 1113216, and I propose to wallpaper it in the same way for now, treating enumerated values for block-size as if they were 'auto' for the purposes of this check. IsNonAutoNonZeroHeight() is only used by nsBlockFrame::IsSelfEmpty, so the worst that will happen as a result of this is that we'll sometimes incorrectly consider a block to be empty (e.g. if it has width:-moz-available), and we might therefore collapse margins in a case where we shouldn't.

Comment on attachment 8555391 [details] [diff] [review] Don't assert when intrinsic size values are used for a block-size property, just pretend they're 'auto' for now r=dbaron. Maybe add a comment pointing this out in relevant bugs? (perhaps the ones in the comment?)
