Video included since I'm not sure how to accurately describe this.
When viewing a media gallery preview on my site, scrolling on the page causes the preview to refresh and resize. If you're watching a video (like my included video to this post), it causes the video to stop and go back to the beginning. The same happens on, PDFs/PowerPoints/etc and you jump back to the top of the document (assuming multiple pages).
In the video, you can see the dimensions of the embedded video change in the Chrome dev tools, but I can't accurately locate them since if I dig in further to the div, it refreshes when I scroll.
Is this specific to my site, or do others experience it? Any ideas of where this resize is coming from and how to disable it?
Note - This does NOT seem to happen to embedded documents or videos in forum posts or other application/content types.
