Summary REGRESSION (r121599): incorrect border scaling when zoomed
Emil A Eklund
Reported 2013-01-15 14:19:54 PST
1. Create a page with an element that has a relative border-width (e.g., border-width: 0.25em), or view the example at http://jsfiddle.net/W2SdF/ 2. Zoom the page in and out. Expected behavior: The border should scale with the rest of the content. Observed behavior: The border scales more rapidly than the rest of the content. This issue doesn't happen with absolute units like px. It also doesn't happen upon changing the user agent stylesheet's base font size (but of course if I change the base font size and then zoom, the problem does appear).

Rebaselined http/tests/misc/object-embedding-svg-delayed-size-negotiation-2.htm on Win in r139834. Weirdly Mac bots still had thin borders. They are covered by an ancient failure expectation from bug 62754.

Thanks Dominic, was waiting for the windows bot to run and forgot about it.
