Closes #29371.
#26053 is a previous related fix that should probably have included this change but did not go far enough.
An interesting part of this is the part that pertains to what should happen when the slider head is not hit (see test cases added in 033fe3f). I've opted to go with the lenient choice, which is to let the user continue to pick up tracking the slider even after the head was missed (but if tracking is lost at any point after that, the tail will miss as usual).
