Bad downloading behaviour on Safari 11.1 after seek

Created by: robertbryer

Environment

The MPD passes the DASH-IF Conformance Tool on http://dashif.org/conformance.html
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: http://reference.dashif.org/dash.js/v2.6.8/samples/dash-if-reference-player/index.html
Dash.js version: Since 2.6.7
Browser name/version: Safari 11.1
OS name/version: Mac 10.12.6

Steps to reproduce

Load, seek to a new point in the stream. (may need to try more than once)

Observed behaviour

Sometimes, dash.js downloads too many segments from a track and nothing from the other track, and much more than the buffer target. It doesn't always happen, so you might need to try a couple of times to see it.

After a period of time it recovers and starts again from the beginning (probably once it has downloaded to the end of the segment availability range), but is downloading all the same segments again.

Sometimes, it downloads each segment twice on its way, like in the attached logs below.
