Draggable jumps to far left edge of window on first drag

Reported by Evan | August 24th, 2010 @ 09:06 AM


Given a right-positioned

initialized as a Draggable, on first drag the
will flash to the left side of the screen and then return to the right side of the screen. Subsequent drags do not trigger the issue. It appears the very first drag, moving the
1 pixel, causes the "left" style attribute to be set to "0". All subsequent drags set the "left" property to the proper offset of the drag.

System configuration

  • Issue confirmed present using Safari 5.0.1 and Chrome 5.0.375.127.
  • Issue confirmed not present using Firefox 3.5.8 and Opera 10.61.
  • Mac OS X 10.6.4

Reduced test case

Attached. Drag the gray box at the right side of the screen one pixel to the left. Expected errant test behavior: the box moves to the absolute left edge of the screen.

    Seems Lighthouse does not escape HTML characters. Above issue description should read "Given a right-positioned div initialized as a Draggable, on first drag the div will…" and so on.
