This reverts commit 543f5ae3.

When this feature was originally proposed, the use cases when <Ctrl><F>
is required because "just typing" doesn't do the trick were not
considered. Two such cases are searching for a ~ (tilde) and pasting
text to search with <Ctrl><V>. Both are now impractical because the
filter popover steals the focus.

Furthermore, we have a few inconsistent state bugs related to this.

Instead of shipping version 3.30 with these regressions and bugs, let's
withdraw this change.
