The generated tooltips for the 'author-info' for the 'acmart' seems to all get stacked on-top of eachother:

A quick look at the output HTML and CSS:

        <div class="ltx_authors">
          <span class="ltx_creator ltx_role_author">
            <span class="ltx_personname">John Doe

        </div>

.ltx_authors_1line .ltx_author_notes:before { content:"*"; color:blue;}
.ltx_authors_1line .ltx_author_notes span { display:none; }
.ltx_authors_1line .ltx_author_notes:hover span {
    display:block; position:absolute; z-index:10;

}

I am admittedly not much of web-programmer, but it looks like all spans get activated by this rule separately. It's probably better to try to gather all of these lines into a single block/tooltip, somehow
