If anyone has any objections, please let me know. ------------------ From: DaytonCL [ Upstream commit ff3f234ff1dcd6d626a989151db067a1b7f0f215 ] Some VTL-class touchpads (e.g. TOPS0102:00 35CC:0104) intermittently fail to release a finger contact. A previous slot remains logically active, accompanied by stale BTN_TOOL_DOUBLETAP state, causing gestures to stay latched and resulting in stuck two-finger scrolling and false right-clicks. Apply MT_QUIRK_STICKY_FINGERS to handle the unreleased contact correctly.
