The first attempt to play HTTP/HLS failed, but it worked after refreshing the page

[mxzhu]

Description

During the initial playback, only the first corresponding .ts data for the .m3u8 was downloaded, and afterwards, it kept downloading only the .m3u8 (without downloading the corresponding .ts files). However, after downloading the .m3u8 several times and then refreshing the current page, the video was able to play normally, with both the .m3u8 and the corresponding .ts files downloading correctly.

Reduced test case

https://codepen.io/mx-zhu/pen/PwYevYx

Steps to reproduce

1.Play video upon page loading.
2.Wait until at least two .m3u8 files have been downloaded, then refresh the page.
