I did some digging into the issue and I think the root cause could be one of these two:

1. Algolia changed some HTML and CSS but because we cloned their CSS in docusaurus-theme-search-algolia/src/theme/SearchBar/styles.css, our CSS is outdated and no longer matches the updated styles.
2. Algolia currently has a bug.

See the attached screenshots. I was comparing the difference between the working HTML and the buggy HTML - the buggy HTML seems to have missing classes that were present in other rows. Adding those two classes fixed the layout issue.

@endiliey any reason why we cloned Algolia's CSS here? Is that the correct way to use Algolia Docsearch?

Its reactjs.org css 😊.

The default one wasnt as nice and iirc is only available through cdn. Also colocated the css so that its swizzle-able easily.

P.S: waiting for stable release of docsearch v3 which is so much smaller in bundle size and came with dark/light theme css. They rewrote it from scratch and no longer relies on zeptojs
