Are you reporting this against any skin in particular?
For example,
On Desktop Improvements (Vector 2022) it explicitly set to "", which should be fixed:
<a href="/wiki/Main_Page" class="mw-logo"> <img class="mw-logo-icon" src="/static/images/icons/wikipedia.png" alt="" aria-hidden="true" width="50" height="50"> <span class="mw-logo-container"> <img class="mw-logo-wordmark" alt="Wikipedia" src="/static/images/mobile/copyright/wikipedia-wordmark-en.svg" style="width: 7.5em; height: 1.125em;"> <img class="mw-logo-tagline" alt="The Free Encyclopedia" src="/static/images/mobile/copyright/wikipedia-tagline-en.svg" style="width: 7.3125em; height: 0.8125em;" width="117" height="13"> </span> </a>
On Timeless, there is no alt, but hover does give the "title"
<div id="p-logo" class="mw-portlet" role="banner"><a class="mw-wiki-logo timeless-logo" href="/wiki/Main_Page" title="Visit the main page"><img src="/static/images/icons/wikipedia.png"></a></div>I assume the report is about Vector 2022. Vector legacy displays MediaWiki:Tooltip-p-logo where the default English is "Visit the main page". I don't know whether it was intentionally dropped in Vector 2022 for some reason.
