Bitchute video embed is broken for blogs

Summary

Video embeds for blogs do not seem to work for BitChute, but does for YouTube - there may be other providers with issues as I had this happen yesterday, and the link was not BitChute (although what it was does escape me): https://www.minds.com/newsfeed/1004763416066465792

Steps to reproduce

1. Take a video from bitchute e.g. https://www.bitchute.com/video/zuHw8YEfiUg/
2. Try to post it in a blog

Platform information

Chromium / Ubuntu 18.04

What is the current bug behavior?

The video does not embed, nothing happens

What is the expected correct behavior?

It should allow the video to be embedded.
