I followed the below steps on Chrome "Version 63.0.3207.0 (Developer Build) (64-bit)". 1. Loaded https://nightly-dot-shaka-player-demo.appspot.com/demo/#asset=offline:1;lang=en-US 2. Selected "Angel One (multicodec, multilingual)" from the drop down. (Tried with the other videos as well) 3. Clicked on "Load" 4. Clicked on "Store" in "Offline" section 5. Disabled network connectivity by all the 3 ways mentioned below: a. Turned to Offline mode in DevTools. b. Disabled networking at the system level. c. Disconnected the network cable. I was not able to reproduce the crash. Is this issue reproduced always? Can I get more information about this?
