Wheel mouse with framebuffer console driver

I’m using an IMPS2 protcol mouse.
I’ve noticed that the framebuffer SDL driver sends button down
events for wheel motion but no explicit button up event.
So if you have two consecutive wheel motion events in the same
direction it looks like the button has been held down when it
should look like a button being pressed twice.–
