This is a reland of commit 5165d20e7238073b0c3e36e83b2f156053459b8f

Original change's description:

[A11y] Fix DCHECK related to missing parent

This fixes a DCHECK caused by an image's child being detached, and
that child object remaining in the cache but not attached to anything.
In the a11y tree, images can adopt children from elsewhere in the DOM via the usemap attribute, which results a lot of special cases in the engine.
