And we tried and confirmed the following:

• It not occurs for the following test content. https://storage.googleapis.com/wvmedia/cenc/h264/tears/tears_sd.mpd
• It occurs in ShakaPlayer Embedded Sample Project too.
• There is no error log when a issue occurs.

Is there a way to improve this issue?

Is there any missing information in the issue description?
