Mozilla, please stop leveling down to others! Recently I discovered that Firefox goes to great lengths to discard <textarea> undo-redo history after it's been changed specifically via JS for web-platform (aka Chrome) compatibility.

Thanks but no. I don't want my textareas undo-redo history to be modified by javascript.

I should have put it clearer: every time the content of a textarea is modified by JS, the undo-redo history is cleared
