Values in property sliders getting tied to mouse position

My mouse position keeps getting tied to random properties sliders. With this bug, whenever I have properties in view, the mouse position is increasing or decreasing random values in the sliders, and I have no apparent way to cancel that or control which ones should react to the mouse position.

I'm having a bit of a double clicking trouble, so some crazy interaction might be happening whenever my mouse clicks a field multiple rapid times.

I'm on Google Chrome / Windows

Reproduce the behavior in Google Chrome on Windows with properties visible, using the linked video as a reference and checking whether rapid double-clicking contributes. Trace the property-slider and mouse interaction entry points; done means mouse movement no longer changes unintended slider values and the affected interaction can be controlled or cancelled.
