Fixing video aspect ratio for Drupal 10 media module's remote video embed

Basically the solution is to add a patch from core that lets you set a maximum size, but you also have to set that per Remote Video view mode to fit the size and aspect ratio it will be shown in. So 960 px for full screen ‘default’ remote video shown in a Node, the node full node display set to show the default display of the media reference field; in a Block or Paragraph, referencing a new ‘small’ or ‘column’ display mode for videos whith a 360px max width.

Not truly responsive.

(EndTB is the project i can look up which patches and exactly which configuration workarounds.)
