Log Message:
-----------
Range APIs do not construct / move trees in tree order (observable by custom
elements)
https://bugs.webkit.org/show_bug.cgi?id=188279
Reviewed by Chris Dumez.
In order to match the spec'ed upgrade order, create a nested custom element
reaction stack
which is used as a holding tank of upgrade reactions during
Range::processContents.
At the end, we traverse the document fragment top-down and re-enqueue each
element to the real
custom element reaction stack in the tree order.
