Video block – how to add “playsinline” attribute

I am using the Gutenberg native block to display a video, hosted through WordPress. I want to use the video basically as a silent background animation. It’s working just fine, except on mobile devices. I have it set to autoplay, muted and loop, but it won’t actually autoplay without hitting the play button. When playsinline is manually added to the <video> tag, it does work.

Can we make playsinline one of the selections in the video block options?

I dug into the Gutenberg packages on github, and from what I can tell, all of the code for the video block actually is set up for allowing the selection of playsinline. Why doesn’t it show up in the WordPress editor?
