Player loads endlessly, but never starts playing (since 3.1.2)

[schmittjoh]

Environment

• [x] The MPD passes the DASH-IF Conformance Tool on https://conformance.dashif.org/
• [x] The stream has correct Access-Control-Allow-Origin headers (CORS)
• [x] There are no network errors such as 404s in the browser console when trying to play the stream
• [x] The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
• [x] The issue occurs in the latest reference client on http://reference.dashif.org/dash.js/ and not just on my page
• Link to playable MPD file: can provide this via email if needed or alternatively more debug information
• Dash.js version: 3.1.2
• Browser name/version: Edge/Chrome
• OS name/version: Windows 10

Steps to reproduce

Load the MPD file and try to start playing.

Observed behaviour

The player continues to load fragments, but never reaches the canPlay event and playing never starts. The same manifest works fine in the 3.1.0 player and also the 3.1.1 reference player. So, it must be some change that was introduced in 3.1.2 (all tested with the official reference player on reference.dashif.org).
