Additional player setup steps

We hit same issues on ChromeOS v132. Interestingly, when testing on ChromeOS v141 there were no issues. Also, when rolling back to older HLS version there are no issues (0.14.17). So some conflict with newer HLS ABR logic and MediaSource API in these older versions of ChromeOS.

I explored bypassing issue by setting startLevel=0 and disabling autoLevel for these specific versions but same issue occurs.

We would like to use latest HLS but this is a blocking issue for us so please fix! Thanks.
