    timeline: Fix dot appearing when clicking on the timeline
    
    The dot caused by the selection Marquee still appears,
    but now it's under the mouse cursor. If the user releases the mouse button it is hidden, otherwise
    if the user moves the cursor to drag&drop then the
    Marquee starts to be visible.
    
    Fixes #2432
