Screenshot

Looks just like the regular page on https://pkg.go.dev/net/http, but with a slightly greyed background. The same greying you get when you search with f, except that the actual search dialog does not appear.

What did you do?

• Navigated to https://pkg.go.dev/net/http
• Pressed f on my keyboard

What did you expect to see?

The "Jump to" dialog.

What did you see instead?

No dialog. Just modal greying of the page background and inability to interact with it.
