  Log Message:
  -----------
  Incorrect image srcset candidate chosen for <img> cloned from <template>
https://bugs.webkit.org/show_bug.cgi?id=211620

Reviewed by Simon Fraser.

The bug was caused by HTMLImageElement not selecting the correct candidate
if it was initially created in a document without a browsing context.
