What are the manifest and license server URIs? N/A

What configuration are you using? What is the output of player.getConfiguration()? everything default

What did you do? Followed by the PR #7218, I found these doesn't work expectedly, at least in unit test:

In practice, MPD:

<S d="1" t="0" />
<S d="2" t="1" />
<S d="1" t="3" />

Remove patch:

<remove sel="/MPD/Period[@id='1']/AdaptationSet[1]/SegmentTemplate/SegmentTimeline/S[t='3']">
</remove>

Replace patch:

 <replace sel="/MPD/Period[@id='1']/AdaptationSet[1]/SegmentTemplate/SegmentTimeline/S[t='3']/@r">
    3
</replace>

Error message:

Expected _class2({ startTime: 3, endTime: 4, trueEndTime: 4, ... }) to equal _class2({ startTime: 3, endTime: 6, trueEndTime: 6, ... }).

What did you expect to happen?

What actually happened? (In some situation?) <remove> and <replace> not working as intended. This seems not related to shared <SegmentTemplate> as PR #7218 is addressing that issue while doesn't help on this issue.

Are you planning send a PR to fix it?
