Bugzilla

Note: I noticed that Chrome disagrees with the spec on what happens when the writing mode changes. (and when that causes the logical size to change, vs. when it causes the physical size to change)

Right now Chrome only seems to notify when the physical size (e.g. the `width`) changes, even though the logical size may have remained the same (if e.g. `width` and `height` were swapped simultaneously with the writing-mode change).

I filed https://github.com/w3c/csswg-drafts/issues/3887 to get the spec clarified.  Here's a testcase: https://jsfiddle.net/dholbert/ce094nxj/

I filed https://github.com/w3c/csswg-drafts/issues/3887 to get the spec clarified, because it's not really clear how writing-mode changes are supposed to be handled right now.  Here's a testcase: https://jsfiddle.net/dholbert/ce094nxj/
