1. If CSS Regions is not enabled (it's turned off in about:flags in Chrome) then the following should be true document.body.style.webkitRegionOverflow == undefined Currently it'll return an empty string. 2. Additionally, in http://adobe.github.com/web-platform/utilities/css-regions-support-matrix/ One of the assertions ('Initial default value for region-overflow') will pass in Chrome Canary with the flag turned off. Chrome should score a 0 with the feature turned off. 3. With this fixed, feature detects would fail fast: https://github.com/Modernizr/Modernizr/blob/b18048b4b4245326d7f6f5a998df58050acf51a9/feature-detects/css-regions.js#L12-17 4. More importantly, this may end up being a false positive in the upcoming @supports functionality (bug 86146) Thanks! (Feel free to rename ticket if I've gotten the details wrong)

This seems to be a Chromium bug, closing.

The bug actually has some WebKit ramifications, too. Keeping it open.

Since Regions are enabled by default in Safari, will close as RESOLVED/INVALID
