The failing tests seem unrelated to this change https://github.com/google/model-viewer/runs/6713537145, I'm now trying another run https://github.com/google/model-viewer/actions/runs/2429981897

[First test run](https://github.com/google/model-viewer/runs/6713537145) produced 5 (unrelated) failures, [Rerun (2)](https://github.com/google/model-viewer/actions/runs/2429981897) produced only 1 failure (still unrelated), and [rerun (3)](https://github.com/google/model-viewer/actions/runs/2429981897) produced 4 (unrelated) failures.

Hi @Caffeinix, it might be related, a jsbin showing the issue would be helpful :smile:

Thanks @Caffeinix! Yes, this is related. Each element of the `iron-list` has `will-change` and `transform` css properties setup, which create a new stacking context, which traps the `paper-menu-button` (and its...

@supermario999 what would be the use-case & expectations? Should the backdrop also take the size of the `fitInto` element? When you set `with-backdrop` on an overlay, it will also block...

That would require its container to set the size (min/max), and there are cases where we want the image to take as much space as possible and notify the parents...
