Very slow server --> MultExcerpt Name dropdown in MultiExcerpt Include macro may not work
For a very slow server the dropdown for MultiExcerpt Name in the MultiExcerpt Include macro may stop functioning if a user clicks the downarrow and types into the input before the REST call to populate the dropdown completes.
It is hard to describe exactly but, in some circumstances, this seems to interrupt the dropdown rendering and it does not recover unless you close the macro editor and then re-edit to start again.
