Dash.js fails multiperiod switching when seamless period switch is not allowed

Created by: aYutaSekiguchi

Environment

The MPD passes the DASH-IF Conformance Tool on https://conformance.dashif.org/
The stream has correct Access-Control-Allow-Origin headers (CORS)
There are no network errors such as 404s in the browser console when trying to play the stream
The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
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://livesim.dashif.org/livesim/periods_60/continuous_1/testpic_2s/Manifest.mpd
Dash.js version: 3.2.1
Browser name/version: Chrome 89.0.4389.90
OS name/version: Mac OS Catalina 10.15.5

Steps to reproduce

Please provide clear steps to reproduce your problem
- set reuseExistingSourceBuffer and jumpGaps to false
If the bug is intermittent, give a rough frequency if possible

Observed behavior

Video playback stopped at period boundary.
The player stops loading media fragments.

I did some research and found that a value of playbackController.getTimeToStreamEnd() at https://github.com/Dash-Industry-Forum/dash.js/blob/v3.2.1/src/streaming/controllers/StreamController.js#L243 is always greater than 0 and PLAYBACK_ENDED event is not fired.
