Thanks for the bug report. It reproduces for me on Safari Technology Preview 163, and spindump indicates the web process (responsible for rendering web page) is busy syncing LocalStorage items after error. It does not reproduce for me on WebKit Nightly build (latest OpenSource WebKit version, which means it might be fixed but not shipped yet.) I think this is a dupe of https://bugs.webkit.org/show_bug.cgi?id=251800.
