This assertion trips on devtools/client/inspector/test/browser_inspector_highlighter-eyedropper-xul.js and devtools/client/inspector/markup/test/browser_markup_remove_xul_attributes.js mochitests when run with apz.allow_zooming=true

The same assertion is hit in bug 1610657.

Attachment: Layers dump

0x7f8e202d9800 has the async zoom container, and the rcd is 0x7f8e318d1800 which is in a different subtree. Presumably we shouldn't be making the former an async zoom container.
