TypeError: htmlspecialchars(): Argument #1 ($string) must be of type string, array given in htmlspecialchars()

Problem/Motivation

When uploading video's via the D10 layout builder modal you get the a quit error like 'Oops, something went wrong. Check your browser's developer console for more details.'

Steps to reproduce

1. Edit a page
2. Add/edit block with media video
3. Upload new video
4. Use a link such as https://player.vimeo.com/progressive_redirect/playback/123456789/renditi...

Proposed resolution

ProviderPluginBase::getVideoId() is expected to return a string - it's being used by ProviderPluginBase::getName()
the implementation in Html5 class returns an array instead

Remaining tasks

Come up with a solution.
Quick fix is to implement Html5::getName() and

• leave the name empty
• use the first value of the array
