Description

The following issue was raised on trac: #63519 by @rlautan

The core/video block that uses a caption has no accesibility name. Adding one as a aria-label or a aria-labbeledby attribute will enhance the accessibility for the block.

Step-by-step reproduction instructions

1. Create a new page/post
2. Add a core/video block
3. Add media and caption to it
4. Navigate to the frontend, and using a screenreader try to focus on the video.
5. Verify that the screenreader announces the video but not the caption
