<p dir="auto">Simple CSS-only solution that doesn't change anything else except lets you see the title text for <code class="notranslate">abbr</code> elements on mobile and desktop consistently:</p>

<p dir="auto">CSS from <a href="https://stackoverflow.com/a/69353021/1201863" rel="nofollow">https://stackoverflow.com/a/69353021/1201863</a>. Tested that the code works in normal text and also nested, for example in an <code class="notranslate"><a></code> link</p>
<p dir="auto">The <code class="notranslate">tabindex</code> makes it selectable such that screen reader users can hopefully also open it. Regarding the value, <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex" rel="nofollow">MDN says</a> <code class="notranslate">tabindex=0</code> "means that the element should be focusable in sequential keyboard navigation" -- it does <em>not</em> put it at the top of the tab stack!</p>
<p dir="auto">Hopefully this covers everyone's (accessibility) requirements by looking like what people expect from a tooltip while also not requiring javascript. I'm kind of blown away that mobile browsers, after all these years, still can't just do tooltips natively...</p>
