I need a WebKit "Ranger" for this question:
Imagine I have the word "Foo" inside an edit field (input type=text
value="Foo") and the word "bar" outside of it, like so: [Foo]bar
If I try to create a Range of the text Foobar, the range will get collapsed.
It collapses because Range::setEnd has a |start| inside the shadow tree and
an |end| outside of it. Specifically, setEnd walks up the parent chain for
both |start| and |end| (to see if they share the same root container), but
doesn't reach the top for |start| because while walking up the parent list
it stops on a shadow node (TextControlInnerTextElement), which has only a
Is this expected? Is this a bug? Is the right fix to have it walk up the
shadow parent for shadow nodes?
PS. I believe this is the root cause for
https://bugs.webkit.org/show_bug.cgi?id=25868, which was a regression caused
by the fix for https://bugs.webkit.org/show_bug.cgi?id=7023.
