Sample

I'm seeing extremely laggy (in the order of seconds) text entry when using the service chat window on trupanion.com, I've verified that the text entry is not slow in Firefox or Chrome.

From a sample it looks like this is a pile of CSS style resolution occurring, presumably on every keypress, as the lag just accumulates as I type.

I'm attaching a sample of the sadness

I cannot reproduce this with built-in Safari on macOS 12.5.
