Videos aren't playing automatically, although it's set to happen.

1. Go to https://test.echopedia.org/index.php?title=Case_67

Expected behavior
The video should automatically start to play on mobile.

• OS: Android 13
• Browser: Chrome 119.0.6045.163
• Extension Version: 3.4.0
• MediaWiki Version: 1.39.5

Additional context
It is known to be buggy on PC as well. Sometimes video doesn't start to autoplay, but when I open source editor and come back, it starts autoplaying. That's only for PC, on mobile devices it doesn't autoplay at all.
