What did you do?

Tried this scenario in the Shaka 4.13.2 version and also in the latest main branch code.

Tried playing Widevine DRM protected Live Dash Stream while the program had started 20 mins ago.Instead of playing from the current position, the player started playing from the beginning of the program. This is a scenario where DVR options are available and manifest has historical LOD available with the timeShiftBufferDepth property.

Note: we are currently using the Shaka 4.11 version, and this issue does not happen there.

What did you expect to happen?
Player should have started playing from the current time.

What actually happened?

Player started to play from the beginning of the program which is not the current live postion.

Are you planning to send a PR to fix it?
Not Yet.

**What are the manifest and license server URIs?**
<!-- NOTE:
  You can send the URIs to <[email protected]> instead,
  but please use GitHub and the template for the rest.
  A copy of the manifest text or an attached manifest will **not** be
  enough to reproduce your issue, and we **will** ask you to send a
  URI instead.  You can copy the URI of the demo app to send us the
  exact asset, licence server, and settings you have selected there.
  Avoid geo-blocked content if at all possible, as the contributors who diagnose
  Shaka Player issues may not be able to access it.
  If you send the URIs to email, the response time and resolution
  will be much higher.

The urls will require authentication and there are encryption details in the manifest. I can provide a manifest after modifying the encryption details. Is the main manifest along with one period example good?
