Thank you for the report! I can reproduce on iOS. Works for me on macOS.

Turns out that this is not a WebKit issue. This video is encoded in a format that isn't supported (H.264 main profile level 6).

We cannot provide further guidance here, but from a quick web search it appears that the topic of formats supported by iOS devices is well covered on the internet.
