Oh, I see; it works if you remove it.  
Using the upload button works because it doesn’t define the mime type in `<source>`.

From [\<source\> HTML media or image source element - HTML | MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/source)

> If the `type` attribute isn’t specified, the media’s type is retrieved from the server and checked to see if the user agent can handle it; if it can’t be rendered, the next `<source>` is checked. If the `type` attribute is specified, it’s compared against the types the user agent can present, and if it’s not recognized, the server doesn’t even get queried; instead, the next `<source>` element is checked at once.

It’s not a bug per se, but yes, It might be a good idea to let the HTML tag check the file and to get the same behavior as the core as well. Will make a PR later unless the team has a better fix to propose.
