Without autoplay enabled, won't be able to seek to the latest progress to start playback when exceeding the live broadcast range.

• [X] The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
• [X] 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://d24rwxnt7vw9qb.cloudfront.net/v1/dash/e6d234965645b411ad572802b6c9d5a10799c9c1/All_Reference_Streams/91d37b0389de47e0b5266736d3633077/index.mpd (Dash JavaScript Player stream->Live (Dynamic MPD)->[AWS] Multiperiod - Number + Timeline - Compact manifest - Thumbnails (1 track) - In-the-clear)
• Dash.js version:5.0.0
• Browser name/version: Chrome 126.0.6478.61
• OS name/version: Windows 11, version 23H2

Steps to reproduce

1. Disable auto-play.
2. Load MPD file:https://d24rwxnt7vw9qb.cloudfront.net/v1/dash/e6d234965645b411ad572802b6c9d5a10799c9c1/All_Reference_Streams/91d37b0389de47e0b5266736d3633077/index.mpd (Using Dash JavaScript Player stream->Live (Dynamic MPD)->[AWS] Multiperiod - Number + Timeline - Compact manifest - Thumbnails (1 track) - In-the-clear)
3. Wait for 6 minutes without clicking the play button.
4. Upon clicking the play button, the player fails to download a new MP4 file, resulting in the buffer becoming empty.
5. Attempting to seek using the play bar does not function correctly.

Observed behavior

Fails to download a new MP4 file. Can't seek.

Expected behavior

Can switch to the current time without any issues.

Thanks!

Probably the initially selected period is not included in the DVR window anymore and is then removed from the MPD. This needs to be checked in more detail, but has low priority for now.
