Subadmin user-add and strange required input fields

[rotdrop]

Adding users as sub-admin master branch and probably a couple of recent versions, at least v22:

server/apps/settings/src/components/UserList.vue

Lines 78 to 85 in 5a469f5

	<!-- hidden input trick for vanilla html5 form validation -->
	<input v-if="!settings.isAdmin"
	id="newgroups"
	:class="{'icon-loading-small': loading.groups}"
	:required="!settings.isAdmin"
	:value="newUser.groups"
	tabindex="-1"
	type="text">

• the comment states it is an "hidden input trick for vanilla html5 form validation", but the input is not hidden
• as long as no groups have been selected the input is empty
• if one of the sub-admin groups are selected the (not-hidden) input just shows the string "[object Object]"

So shouldn't this be changed:

• if still required as that "HTML5 form validation trick" then it should be really hidden, as it is really confusing to have this strange buggy input field in the UI
• if it is supposed to function then this "[object Object]" string value somehow does not look right and perhaps should be replaced by a comma separated list of group-ids or so
