The page https://www.vox.com/future-perfect/352359/milk-dairy-schools loads forever in GTK MiniBrowser and Epiphany using WebKitGTK 2.44.1 and 2.44.2. It finishes loading almost instantly in Firefox. It seems polyfill.min.js just never loads and there is either no timeout or an extremely excessive timeout. 2039938 1 mcatanzaro 2024-06-05 13:36:34 -0700 This bug is not deterministic. It happens about half the time. 2039951 2 mcatanzaro 2024-06-05 14:16:46 -0700 This is an HTMLMediaElement bug. It calls Document::incrementLoadEventDelayCount and then never calls Document::decrementLoadEventDelayCount (at least not within a reasonable amount of time). Possibly a GStreamer backend bug? If you can't reproduce the bug on the first try, just reload the page a few times until you can. (There is also a loader bug here causing Stop to fail when this happens, bug #242248. Let's treat that separately, though.) 2040046 3 philn 2024-06-06 01:25:29 -0700 Works fine in MiniBrowser/main. 2040072 4 mcatanzaro 2024-06-06 03:37:44 -0700 It was happening for me yesterday using MiniBrowser from yesterday's git main. But today I cannot reproduce it anymore. I'm now seeing a crash instead, bug #275205. 2040235 5 karlcow 2024-06-06 22:04:20 -0700 fwiw, it loads instantly in Safari.
