As a workaround .asDelta().isEmpty works, but first time the contents is removed in RTE. Running a dummy rte.asDelta() fix this. Seems like another bug?

asDelta intentionally clears the component value, probably because the delta value is not synchronized with the HTML value unless asDelta has been called previously. It would thus always be empty even if there is an HTML value. So mixing asHtml and asDelta is not quite supported by the component.

OK, this is only a work around for the bug. Could test for "<p><br></p>", but feels that is even more dirty workaround
