Nit - perhaps you could factor this out into a helper function, and use it both here and in `-_setFindInteractionEnabled:` below.

Nit - we usually don't abbreviate local variable names. Maybe rename to `position`?

Probably not a real risk here, but typically doing subtraction to determine ordering can introduce overflow, so it’s better not to use that pattern.

Reopening to attach new patch.
