Regression: Slash no longer works to focus the search field

[justinmc]

Describe the problem

Go to any docs page on https://api.flutter.dev/. Press slash on the keyboard. The search field will be focused.

This no longer works on https://main-api.flutter.dev/.

Expected fix

Pressing slash should focus the search bar. I love this feature and use it all the time! Originally added in https://github.com/flutter/website/issues/8996.

On which browser(s) did you experience this issue?

Chrome

Additional context

I'm on Mac.

FYI @parlough

I would like to fix this problem.
