Reproduction steps

In a DASH stream with the provided manifest, ExoPlayer incorrectly calculates getAvailableEndTimeInManifestUs in DashMediaSource. Specifically, when it reaches the calculation for periodStartTimeInManifestUs + index.getTimeUs(lastAvailableSegmentNum) + index.getDurationUs(lastAvailableSegmentNum, periodDurationUs), ExoPlayer calculates 68812608000000 for adaptationSetAvailableEndTimeInManifestUs in the video AdaptationSet, but 68812647999999 for the audio AdaptationSet. Due to ExoPlayer selecting the minimum of these values, it uses 68812647999999, resulting in a windowDurationUs of 86399999999 (and sometimes it changes to 86399979999) instead of 86400000000.
index.getTimeUs(lastAvailableSegmentNum) function return incorrect value and index.getDurationUs(lastAvailableSegmentNum, periodDurationUs) works fine.
This discrepancy appears when the segment number falls within the range 34359740-34999999.

Below is the manifest used:
