Video of bug happening

There is a noticeable lag in the text while typing, both on iOS and Desktop, using the latest versions of Safari on particular textboxes.

We've tested this bug is easily reproducible on both the xcode simulator, and is worse on an actual device.

This issue does not happen in older versions of Safari, or other browsers.

You can test this by clicking on the Ask Question box on https://mylo-ricnej17u-mylomindslive.vercel.app, and trying to type and then delete some text.

Attaching a video for reference.
