Web UI (HTML/CSS/JS Interface Widgets)

I seem to be having trouble getting range sliders to work properly. When mousing down on the slider “handle” and dragging, it may move for a short distance but then shortly stops responding. It seems like it stops processing if the mouse cursor moves off of the handle. This is on 4.22.3 editor on Windows 10, with the player controller input mode set to Input Mode Game and UI, with mouse transparency enabled on the web widget. Maybe it has to do with the new mouse-transparency functionality or my input mode?
