Range.enlarge test failing in Safari 7.0 and Chrome 37

[Olek Nowodziński]

Test /dt/core/dom/range/enlarge.html#test_enlarge_element12 fails in latest Safari 7.0 that comes with OSX 10.9. It's also reproducible in Chrome 37 (see #12221).

The root of the problem is the following condition: ​https://github.com/ckeditor/ckeditor-dev/blob/major/core/dom/range.js#L1039

In this case sibling is empty <b></b> (<p>Test <i><b></b>[Enlarge]</i></p>). Unlike previous versions, Safari 7 considers sibling.$.offsetWidth to be 1 at that point, while in other browsers it is 0. So the conclusion is that empty elements may have some width, which seems to be a regression in browser's engine.

That particular test fails since CKeditor 4.0 in Safari 7 which makes it clear that we're facing Safari regression.

Related bug in Chrome: #12221.

I submitted a bug to Webkit: ​https://bugs.webkit.org/show_bug.cgi?id=124037.

Also reported for Chrome 37: ​https://code.google.com/p/chromium/issues/detail?id=395136

I pushed a commit to major (7d732b3) that marks that particular test as a regression in Safari.

I pushed ​git:b46bd06 with a workaround. It seems that the patch will not be provided soon.

Chrome team claims to have this issue fixed ​https://bugs.chromium.org/p/chromium/issues/detail?id=395136#c14. Wondering how long will it take for WebKit team to fix it.
