Yeah, via [MDN](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand), Firefox \< 89 had bugs with text manipulation:

> Before Firefox 89, manipulating the content of `<input>` and `<textarea>` elements using `Document.execCommand()` commands requires workarounds (see [bug 1220696](https://bugzil.la/1220696)).
