Hi Team,

I was going through some GitHub repos and came across following JSFiddle:

Link - https://jsfiddle.net/1ratc76L/5/

GitHub Issue - https://github.com/cburgmer/rasterizeHTML.js/issues/216

I tried to load this on desktop (macOS 13 using Safari 16.1 and STP 157 - Private Mode as well) and it does not load for me, I closed other apps as well to see if it is due to RAM issue but it was still not loading and I get beach ball as well while trying to interact with the browser UI.

It does not lead to any crash so I don't have any crash logs but it is something which can make Safari to halt on page loading.

Just wanted to raise it as bug so it can be fixed.

Thanks!

It's 11 MB, so not too surprising. But Chrome manages to do better in terms of not freezing the renderer process, and JSFiddle UI becomes responsive eventually. Our WebProcess freezes while still showing JSFiddle's loading UI.
