Cursor hover highlighting in app grid when cursor is hidden by touch screen input
Screencast_from_05-07-19_06_32_05
When I slide the app grid up/down using touch input, the app icon where the cursor was at before being hidden is highlighted as if the cursor is hovering over it. In the attached video I show the position of the cursor in the end by using touchpad input. In the video I am sliding on the empty part in the right, so the touch input is not over the highlighted icons, or any other icons.
"Cursor hover" should be disabled as long as the cursor is hidden by touch input.
The attached video is recorded in a Wayland session. Although the bug exists in the X.org session, it is slightly different; as the cursor actually follows the touch input. To reproduce the bug in X.org, you will have to touch somewhere outside an icon, then slide towards it and release there.
