Searching nightly-rustc docs is broken: "Unhandled Promise Rejection: Error: not a roaring bitmap: 101"

Searching nightly-rustc docs currently produces no results, and spins forever.

In my browser's dev console, I see this error:

• Unhandled Promise Rejection: Error: not a roaring bitmap: 101

Possibly caused by the stringdex updates in #147002.

Okay, I found the problem. You can see it by checking the Help button on the tidy page and comparing it with the root page.

The root was built with the nightly compiler, as expected, but tidy's docs are built with beta. As you can see, the result does not work.
