This doesn't happen in Safari 5.1, but happens in ToT (and Chrome 20, etc.).

Driveby comment: To cater for the RubyRun case you're opening up isSelectionRoot() to all inline blocks and tables. This might be fine, but I think you need more tests to show that's the case.

This might be fine, but I think you need more tests to show that's the case. Thanks for the comment. Since isSelectionRoot() has already returned true for all non-anonymous inline-block objects, I just opened it up for anonymous inline-block objects as well. Do we have anonymous inline-blocks objects (or anonymous inline tables) in WebKit other than RubyRun?

Do we have anonymous inline-blocks objects (or anonymous inline tables) in WebKit other than RubyRun? Seems like this could happen with Tables. Julien can probably tell you.

We can't have anonymous inline tables at this time as we haven't implemented this (see bug 15365, the bottom line is that it's non-trivial). Beware that it is expected and something we will want to fix someday though.

It was added in http://trac.webkit.org/changeset/12986 but I don't think we need it anymore. Removing this line will make PseudoElement's capable of being selection roots. Note that now the code is if (!nonPseudoNode()) return; it'll also make the anonymous renderers inside them, and :first-letter, etc. all into selection roots.

I don't think this patch is right though. The original check was: if (!node()) return; I changed it to be: if (!node() || isPseudoElment()) return; in https://trac.webkit.org/changeset/136744 and then I encapsulated that to: if (!nonPseudoNode) return; in https://trac.webkit.org/changeset/137336 So this patch just enabled all anonymous RenderBlock (and all subclasses) as being selection roots which doesn't seem right without more tests. Also the ASSERT(node() || isAnonymous()); is a truism. Every renderer is either anonymous, or has a node.
