This commit fixes the style of the field, which was pretty broken since the Owl conversion. It also bring back the tooltip (as in legacy) when the button is clicked. The button now only shows the tooltip if the text has been copied successfully to the clipboard, and not appear when it is not allowed or not available in the browser. Tests have been added to assert those behaviors.
