How can I make Safari understand the mkv type in the accept attribute of input[type=file]?

Question

JavaScript

There is a code

<input type="file" accept=".mkv,video/x-matroska,video/*">

In normal browsers, everything works as it should, but safari does not allow loading mkv.
What to write in accept for safari?

Add to accept video/x-matroska and .mkv
