Search box doesn't work after navigating to the search result

[hudochenkov]

1. Open search by clicking in the search field.
2. Enter query, e.g. 1password.
3. Navigate to the first result.
4. On new page click on search field — nothing happens, and there are errors in the console.

500 (Internal Server Error) might be unrelated. It errors, because payload has a lot of gibberish after JSON.
