236957 - Selection code creates ranges that cross anon content boundaries.

Status: NEW

(Core :: DOM: Selection, defect, P5)

Description

[Johnny Stenback (:jst)]

Followup bug to bug 236270. When selecting on a webpage, it's possible to end up
with DOM range objects that start in the document's "real" DOM nodes, but ends
in anonymous content. This confuses the content iterators, if nothing else. See
testcase in bug 236270.

Attachment: Simple testcase how range methods interact with anonymous content

Maybe this is useful (if not, I'm sorry). Here is a simple testcase that shows
how the range methods interact with content/anonymous content.

Also see bug 236796.

[Boris Zbarsky [:bzbarsky]]

So with bug 372086 fixed it should no longer be possible to create a range which has one end in anonymous content and the other in non-anonymous.  Does that help with this bug?

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority and severity.

If you have reason to believe this is wrong, please write a comment and ni :jstutte.
