Description Jon Lee 2014-06-25 10:42:57 PDT
Height of a single CSS region is not being respected. Instead, it inherits the height of the named flow. This only occurs when one CSS region is defined for a particular named region, see attached test case.

Test Case

The region height is correct when I look at the test case. What you're seeing is overflow.

try these to make it more apparent

- set overflow: hidden
- check the region height in the dev tools
- add a border to the region

As Alan says, the test seems to behave correctly. Were you expecting the blur to apply ONLY to the region border box, without affecting the overflow? This doesn't seem to be the case for non-region boxes either.

Hi Jon,

I suppose you compared this to Safari 7 when you marked it as a regression. The reason you are seeing this difference between Safari 7 and the newest code in Nightly is because Safari 7 was not painting regions overflow, at all. This has been fixed some time ago in https://bugs.webkit.org/show_bug.cgi?id=118665. 

Please let me know if there is another problem that we are missing.

Thanks for the clarification. Closing as dupe.
