[Bug]: Pressing `ctrl+f` a second time does not allow native search

[susnux]

Affects only master.
This is a regression as this was fixed a long time ago already for the old design of unified search.

Problem

When pressing ctrl + f the unified search is focused and opened.
Pressing ctrl + f again still prevents default behavior.

Solution

Pressing ctrl + f when unified search is already open should be ignored by unified search and the event must not be prevented, moreover the unified search should be closed to allow native browsers in-app-search (e.g. looking for some specific text).

[susnux]

Moreover ctrl + f opens unified search even in apps with in-app search

When being in the files app the expected behavior is:

• ctrl+f = focus the in-app search
• ctrl+f again = use native browser search instead

But since the latest changes of unified search the unified search is always opened.

This, along with many other pending issues, has been fixed here: #62605

Will mark it as ready tomorrow
