Hi, Youenn!

Bug is still reproducible with MacOS Ventura 13.1 + Safari (Version 16.2 (18614.3.7.1.5))

I added new sysdiagnostics file:

If the bug fixed with https://bugs.webkit.org/show_bug.cgi?id=247310 , Do you know which version a correction could be expected with?

Same, the issue is existed in 16.2 (18614.3.7.1.5) on my Mac Intel Ventura 13.1 (22C65)

I can also reproduced the issue on Safari Technology Preview Release 160 (Safari 16.4, WebKit 18615.1.14.3)
