Please see en:User:Anomalocaris/sandbox/Lint Test, where I show that
<span something>''<div something>Foo</div>''</span>
fails to generate a proper div-span-flip lint error, where the italic markup can be replaced with <small>...</small>, <i>...</i>, or <b>...</b>. What's going on here? Note: I discovered this as I was trying to diagnose the div-span-flip lint error in en:Wikipedia talk:New pages patrol/Coordination. —Anomalocaris (talk) 08:19, 18 August 2022 (UTC)
