Created attachment 389471 [details] sample of process Using STP 99 I have found that on a few occasions, page loading has 'just stopped' - but just within a specific tab/for a specific site. For example this morning hangs are on 'hotukdeals.com', yet I can navigate on netflix (which I have open) and open up a new page like http://www.bbc.co.uk. The issue has previously affected other sites. I previously raised https://bugs.webkit.org/show_bug.cgi?id=201822 -- and this issue has some similarities - but that had global effect. This is much more isolated I don't appear to have any issues with the site itself from mobile (iOS) or indeed using chrome on the same mac. I do have most of the experiments enabled ( Will take some diagnostics then add further notes I do have a sysdiagnose but am wary of posting here
To add - I was able to open up the same web page that was hanging just fine in a STP private window. Closing the regular window and trying to reopen and go to the same URL however would just hang.
closing STP and restarting, I was able to go to the same hotukdeals URL again with no problem
> I do have a sysdiagnose but am wary of posting here That's fair. Could you please report this via <https://feedbackassistant.apple.com> with the sysdiagnose, and post the feedback ID here? Please specify the time when this happened, to make it practical to find in sysdiagnose logs.
thanks. feedback id is FB7563493 Added a new sysdiagnose from similar behaviour today
