iFrame video becoming a keyboard trap

We have several Rise tutorials that use YouTube content embedded using iFrames. Doing accessibility testing, we recently discovered that these become keyboard traps. Users can tab into the content and play it, but the standard guidance of using esc to navigate out of the video isn't working and tabbing through also doesn't seem to work. Does anyone have insight into what we need to do to make this content fully keyboard accessible? Has anyone else had this issue? Thanks!
