Breaking: Frontend UI poof bug

The UI doesn't load in, so search doesn't work (null err from `docsearch.js`).

I tried to debug it, but the file is _uglified_, so it's too difficult to debug (keep an eye out for a feat request to un-uglify these so we can help you guys debug).

More context, screenshots, and [very dirty] workarounds in the [Docsearch Discord thread](https://discord.com/channels/1171089640443367494/1326435893447233618)

**TL;DR:**

1. 

2. This prevents generating the HTML code:

```html

The ultra-dirty workaround is to copy+paste this into `source/_templates/layout.html` to inject this directly in instead of awaiting generation. The other js containing the api keys and such still spawn np.

Start by examining the uglified `docsearch.js` referenced in the report and the generated search markup around `source/_templates/layout.html`. Reproduce the null error and compare it with the Discord thread and the provided workaround; done means the UI loads, generates the search HTML, and search works without the workaround.
