For completeness also tried the CSS solution from this SO thread

https://stackoverflow.com/questions/34276581/display-abbr-and-acronym-on-mobile-devices

Didn't work either, not sure if something else was interfering 

 
@media screen and (min-width: 0px) {
    abbr[data-title] {
        position: relative;

        /* ensure consistent styling across browsers */
        text-decoration: underline dotted;
    }

    abbr[data-title]:hover::after,
    abbr[data-title]:focus::after {
        content: attr(data-title);

        /* position tooltip like the native one */
        position: absolute;
        left: 0;
        bottom: -30px;
        width: auto;
        white-space: nowrap;

        /* style tooltip */
        background-color: #1e1e1e;
        color: #fff;
        border-radius: 3px;
        box-shadow: 1px 1px 5px 0 rgba(0, 0, 0, 0.4);
        font-size: 14px;
        padding: 3px 5px;
    }
}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
