Describe the issue

Related and a possible duplicate of #39081
Seems to be a duplicate of #37206 as well, which is for 5.2.1, but the issue is still present in 5.3.1

As described in the latter issue, a use case is to show a loading... text while the actual content is retrieved via ajax

Calling .setContent() on a popover that is already shown, hides it.
