Look into removing the resize observer

We may be able to check the size of the element every frame instead.

The resize-observer polyfill polls with getBoundingClientRect, and resize-observer-polyfill uses a global mutation observer watching everything. I think maybe the sync reflow option might be preferable since we don't know what else will be on the page. This is an interesting solution as well

Also, the resize observer is chrome only for the most part
