[REDUCTION] Test Case

Noticed while manually testing fast/forms/slider-zoomed.html

Further reduction attached.

The <input type="range"> slider is "stuck on following mouse events"
when a generated mouse event hits the slider. I have a feeling this
may be problematic.

Maybe when SliderThumbElement::startDragging is called, it should
check to see there was a real user action behind it, otherwise it
should act as just a mouseup/down combination without enabling
dragging?
