Bug 1716863 - Make HTMLEditor::HandleInsertText() climb up the tree when Selection is in elements which cannot have text nodes r=m_kato

Browse Source 
In most cases, it's called with selection range which is collapsed in a text
node, but otherwise, the selection may be in an element which cannot have
text nodes.  Therefore, before handling the insertion, it should look for
ancestor element which can have text nodes.

Note that this patch makes inserting text immediately before an inclusive
ancestor element whose parent can have a text node.  However, both Blink and
WebKit ignores if there are invisible/empty inline nodes.  So, even with
this patch, Gecko keeps failing in some tests of the WPT.  It should be handled
in a follow up bug because doing it requires complicated code.
