I can't reproduce this with Safari Version 13.1.2 (15609.3.5.1.3), but can running the GTK mini-browser built from commit hash https://github.com/WebKit/webkit/commit/271d9289eac9aea2e2ba04f4520ef20317c16bb7.  At least, I can reproduce _a_ crash in the mini-browser...I'm not seeing the backtrace dumped to stdout, so I'm not sure it's exactly this same thing.
