I don't like this for the reason Robert mentioned. It makes the list
behave differently based on the number of items in the list. This is
not the usual behaviour of lists in any other UI context the user will
be familiar with so it would be something we are teaching our users to
do. This makes the burden on it's usefulness higher than average. In
this case I think the theme is to blame. Normally a selected button is
brighter than an unselected button so the theme is forcing the user to
learn something new and opposite to expectation so the burden on it's
usefulness is higher than average. Assuming making the selected button
subdued doesn't have some huge benefit here it should be made to conform
to standard user interface conventions.
