Describe the solution you'd like

As discussed earlier, seeking over an interstitial should maintain the original seek target when returning to primary. The RESUME-OFFSET shall be ignored.

The interstitial-controller has a shouldPlay state flag used to resume playback after source resets. I suppose a similar seekTarget could be maintained when a seek is issued and interrupted by interstitial playback. This target could then be used when resuming primary after the seek interrupting break.
