Dash.js: Seek to 0s in Firefox 67.0~70.0.1 causes playback to stop - also on 3.0.1

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

Dash.js version: v2.9.3
Browser name/version:
- Mozilla/5.0 (X11; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0"
OS name/version:
- Arch Linux
- Ubuntu 16.04
- Windows 8.1 (seams to be slightly harder to reproduce. Takes 2-3x as many seek events)

Steps to reproduce

Load video to dashjs based player like http://reference.dashif.org/dash.js/v2.9.3/samples/dash-if-reference-player/index.html
let the video play a little (~2s)
seek (outside of buffered range seams to help reproduction)
wait ~2s and goto 3.
seek to 0s - usually stops the playback (very rarely other seek targets seam to trigger the problem but 0s gives most consistent results)
if not reproduced goto 3.

I'm typically able to reproduce the problem 2-3 iteration (20-60s)
Example JS console interaction triggering the problem (clicking on seekbar directly reproduces the problem just as well).

var elem = document.getElementsByTagName("video")[0]
elem.currentTime=0 // wait ~2s
elem.currentTime=10 // wait ~2s
elem.currentTime=20 // wait ~2s
elem.currentTime=30 // wait ~2s
elem.currentTime=40 // wait ~2s
elem.currentTime=50 // wait ~2s
elem.currentTime=10 // wait ~2s
elem.currentTime=0 // wait ~2s
elem.currentTime=20 // wait ~2s
elem.currentTime=30 // wait ~2s
elem.currentTime=40 // wait ~2s
elem.currentTime=0 // playback stops indefinitely

Observed behaviour

After seeking few times (see "Steps to reproduce") and then to 0s the playback stops while the player ui remains in playing state with seekbar at previous playback time. Buffer ranges seam to be sufficiently filled.

Contrarry to screenshots below the problem does not seam to be reproduced only on lowest bitrate/resolution.
firefox_freeze2

Console output

>> Marks code input to JS console. This problem is also reproducible (although harder due to my butter fingers) by clicking on seekbar but I think using JS console gives slightly more informative log.

If I'm able to enable some higher debug levels or provide more detailed information I'll gladly do it.

Hi @epiclabsDASH

I have tested today with http://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html (commit https://github.com/Dash-Industry-Forum/dash.js/commit/fd2c359d14e0a3c9fd74d70ddff2669b62e016c8) on https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd and it seams harder to reproduce (probably 3x as many seek events required) than v2.9.3 and nightly build I've tested 13 days ago and the logs seem to be slightly more informative.

Hi @epiclabsDASH

I've seen that you are preparing the v3.0.1 release https://github.com/Dash-Industry-Forum/dash.js/commit/13745c6812da3130638ac90abea577511b960f32 and done another round of testing
Unfortunately the reference player for this commit still exhibits the posted problem
