Issues with Facebook Theater view (image preview)

[cyphersweet]

I ran into a bit of an issue when attempting to archive a Facebook page; namely that Theater (the image preview screen when clicking on an image) does not capture properly.

Theater does not work at all if captured on a local browser, which is understandable for reaosns mentioned in [https://github.com//issues/664](this issue). However, remote browsers also have an issue replaying Theater: in Chrome, the preview often never stops loading a black screen; Firefox 68 acts similarly, but Firefox 49 can render the image...but not the comments or other metadata. Curiously, replaying a Facebook page captured remotely on a local browser makes it work correctly...sometimes.

Is it possible that this could be remedied?
