Volumio web UI location progress bar interferes with iPad swipe gesture

When playing a song, the progress bar in the Volumio web interface on an iPad is located in the center at the bottom of the screen. At this exact location the iPad shows a horizontal bar (white or black) that handles swipe gestures. This bar overlaps the process bar and prevents the user to move the playing position. When a user tries to move the playing position, the iPad swipe gesture is handled instead resulting in swiping between apps.

My request is to change this in the UI.

With kind regards, Dennis
