The issue you've linked is different from this page.

On this page you can definitely see a video tag:

but for some reason it failed to load. Definitely website's error.

In this issue though https://instantview.telegram.org/contest/wxyz.com/template36/issue3/

there are no unsupported video blocks. this script was included just for collecting stats for website I guess.

Here's an example with same widget that has a working video https://www.wxyz.com/entertainment/cma-awards/cma-awards-co-hosts-brad-paisley-carrie-underwood-will-balance-honoring-vegas-victims
