Google search results include "Null safety" in the title

When searching for a Flutter API, the "Null Safety" banner is included in the search result:

The title of the page is correct:

<title>AnimationController class - animation library - Dart API</title>

But the text of the page uses a <span> tag:

<h1><span class="kind-class">AnimationController</span> class     <span class="feature feature-null-safety" title="Supports the null safety language feature.">Null safety</span>
 </h1>

Hmm. I know very little CSS/HTML, though I imagine the problem is that the null safety span is in the <h1> block. Some other way of ensuring proper alignment with the heading will be needed.

This will impact other tags that go in this space, e.g. category.

This appears to have been fixed accidentally, possibly by #2455. The words "Null safety" no longer appear in the link title in google searches -- now they are back to the text, where they belong:
