User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36 Steps to reproduce: When I call getBBox() of a SVG element where an empty text element is contained, the returned rectangle seems to be wrong. Actual results: As a result I got always a rectangle with the x/y values of the origin (0,0). Expected results: I assume that an empty text element is not used for the calculation of the bounding box. In my attached examples, there a two groups, one without an empty text element and one with one. For me, both bounding boxes should be the same (100/100 x/y and 100/100 width/height), but they aren't.

And it's on all Windows 7 *sigh* https://hg.mozilla.org/integration/mozilla-inbound/rev/6a99a44e4b18

[Approval Request Comment] Bug caused by (feature/regressing bug #): bug 839955 User impact if declined: bounding boxes of SVG text may be calculated incorrectly. The area covered may also be calculated incorrectly leading to a greater area than necessary being repainted. Testing completed (on m-c, etc.): landed on m-c with tests Risk to taking this patch (and alternatives if risky): could back out bug 839955 and not take the rewritten SVG text support but we'd lose all the new features like underlining and various bug fixes that CSS text frames brings. String or IDL/UUID changes made by this patch: none.
