MPD Anchor doesn't set player end time

[giorgos-epitropou-obs]

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: https://dash.akamaized.net/dash264/TestCases/1a/sony/SNE_DASH_SD_CASE1A_REVISED.mpd
• Dash.js version: 4.0.0
• Browser name/version: Chrome 90.0.4430.212
• OS name/version: Ubuntu 20.04

Steps to reproduce

1. Open reference dashif reference player (https://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html), select any mpd (in this case, first available option for static mpd)
2. Add #t=10,20 at the end of the mpd uri.
3. Press Load button

Observed behavior

Most of the times, playback starts at startTime, but it does not stop/pause at EndTime (#t=startTime,EndTime)

Console output

Start time from URI parameters: 10 

Expected behavior

I tried with different manifests and different time periods, but while start time is set correctly, it never stops at EndTime.

We do not support endtimes via MPD anchors yet
