Forums typing code in a post freezes / lags for seconds while typing.

For some reason typing in posts containing code blocks sometimes makes typing lag, such as here:

[UE5.1.1, Feature Request] Avoid handling input for critical editor controls? - #10 by Roy_Wierer.Seda145

it’s not the browser freezing, just the text area. Nothing strange in the network activity, no errors in the console. Nothing changed on my side this behavior just started within the last few months.

I have a similar issue with the forum, might not be a code block related as i cannot see the post in question anymore it freezes up the tab/browser

that post in particular. May or not be related
