[Docutils-develop] Patches for html5_polyglot video support

[Agathe P. <doc...@mi...>]

Hi,

As discussed in docutils-users, please find attached two patches to 
improve docutils video support. Please let me know when they are merged 
(I see last revision is from 2021-11-23). I will send other patches to 
improve video support further while trying to keep the "image" node.

Bests,

Agata.
