That's a feature.  You can do the same one line at a time with
"C-u 1 C-v".  Using the scroll bar invokes the same commands, so it
behaves the same.  It has nothing to do with the appearance of the
thumb.

Really?  How do you move the thumb and to what position on the bar?

And what happens if you click on the stepper (that tiny arrow at the
top of the scroll bar)?

Those are entirely different issues, unrelated to the size of the
thumb when all of the buffer is on display.
