LL-HLS Playback with Safari, ext-x-part tag support

I am trying to playback live content generated using Apple tools setup with Safari Browser, and having difficulty playing back.

Here is more information of my Server setup:

%tsrecompressor -c -O 224.0.0.50:9121 -L 224.0.0.50:9123 -P 224.0.0.50:9125 %mediastreamsegmenter --part-target-duration-ms=200 -f /usr/local/Cellar/nginx/1.23.4/html/ -t 1 224.0.0.50:9121 -D %cd /usr/local/share/hlstools %go run ll-hls-origin-example.go -dir /usr/local/Cellar/nginx/1.23.4/html -http :443

I am able to playback the content using hls.js demo player and the above Server set-up.

I do see a "Failed to load resource: Plug-in handled load" error and don't see any content being played. Any ideas as to how to work around the error? Makes me wonder does Safari support ext-x-part tag at all? Thanks!
