There are still open issues, but I think the state should be good enough for some Nightly testing.


Need to see what all tests breaks if we enable by default.
So I wouldn't land before all the test results

ok, there is one failure
TEST-UNEXPECTED-FAIL | /custom-elements/builtin-coverage.html | slot: Operator 'new' should instantiate a customized built-in element - assert_equals: Cloning a customized built-in element should succeed. expected function "class extends HTMLSlotElement {}" but got function "function HTMLSlotElement() {

but looks like that fails for other elements already.
I wouldn't be too surprised if this causes some regressions, so backout is possible.
But shadow DOM is so rarely used feature that it is hard to get enough testing without keeping it enabled.

All the compat data on this is basically still accurate with this change — it still isn't really available anywhere. All I've done is to update the entry on the Experimental features page to say it is enabled in Nightly in 62:

Shouldn't this bug be a dependent of bug 1205323?
