Webcomponents aren't enabled by default, and shouldn't be used, so do you have them enabled or what?

For reference, something has changed in FF 50, since this crash did not happen in FF 49. (Both with dom.webcomponents.enabled, of course.)

Pretty sure I'm hitting that in https://crash-stats.mozilla.com/report/index/d0e6c3cc-05e6-4f7c-afd2-8c6d12170312 when navigating to https://www.chenhuijing.com/blog/we-need-to-talk-about-opera-mini/

dom.webcomponents.enabled = true is totally unsupported configuration of course. It is for the deprecated ShadowDOM v0 API which no one should implement.

Mass wontfix for bugs affecting firefox 52.

createShadowRoot is the old API but it still exists in the tree (not exposed to the web) so let's leave this open to track removing it.

Even with a test using attachShadow and replacing root with div so that attachShadow actually work can't reproduce this. Please reopen if one can somehow reproduce this these days.
