This should be a simpler setup. We keep every element being a direct anon child of the text control, and special case the reflow of the spinners / clear button, to subtract that size from the other elements. This fixes the bug by ensuring that the editor and placeholder are sized and positioned in exactly the same way. Differential Revision: https://phabricator.services.mozilla.com/D108305
