http/tests/media/hls/hls-webvtt-tracks.html [ Timeout ]
These tests time out because the external subtitle track doesn't load. See https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/969 Supposedly this all works now thanks to hlsdemux2, but we can't use it yet in WebKit because: 1. We don't use playbin3 by default yet 2. Network access was hard-wired in hlsdemux2, preventing its use in a process that is network-sandboxed.
