If a validation message could be cloned, it may be broken by the same cause as bug 61909.
I guess cloning validation message nodes doesn't cause critical problems such as crash. However, no one won't hide a cloned validation message.
Validation message nodes should not be cloned.
Oops, I was wrong ;-(

How about to use layoutTestController.shadowRoot() and
check pseudo id for clones shadows?
Another idea is to give r+ to Bug 62432, then use elementRenderTreeAsText(),
which allows us a kind of reftests ;-)

It's reasonable. Thanks!

Hi Kent-san, I'm sorry for slow response...
And during my lazy time, layoutTestController.shadowRoot() is obsoleted.
Could you rewrite this with window.internals.shadowRoot() ?
I'm sorry again for the inconvenience.
