There is a corner case where this does not work in Split view.
One example is a top-level symbol, such as CONFIG_64BIT.

For x86, CONFIG_64BIT is located at the top-level,
and it does not belong to any menu.

This works in Single and Full views.

[1] Choose Full view  (default)
[2] Select "64-bit kernel"
[3] Choose Single view and Full view back-and-forth
[4] "64-bit kernel" is still selected


However, this does not work in Split View:
[1] Choose Full view  (default)
[2] Select "64-bit kernel"
[3] Choose Split view
[4] "64-bit kernel" is not selected


The Split view never works in a consistent way.
I will consider whether I should fix such a corner case or not.
