414 					// ----------------------------------------------
415 					//
416 					// Versions of Internet Explorer older than 9, are buggy in

418 					// movements, when the following conditions are true:
419 					//
420 					//  * The range is collapsed.
421 					//  * startContainer is a contenteditable text node.
422 					//  * startOffset is 1.
423 					//  * There is a non-conenteditable element left of the
424 					//    startContainer.
425 					//  * You attempt to move left to offset 0 (we consider a
426 					//    range to be at "frontposition" if it is at offset 0
427 					//    within its startContainer).
428 					//
429 					// What happens in IE 7, and IE 8, is that the selection
430 					// will jump to the adjacent non-contenteditable
431 					// element(s), instead moving to the front of the
432 					// container, and the offset will be stuck at 1--even as
433 					// the cursor is jumping around the screen!
434 					//
435 					// Our imperfect work-around is to reckon ourselves to be
436 					// at the front of the next node (ie: offset 0 in other
437 					// browsers), as soon as we detect that we are at offset 1
438 					// in IEv<9.
439 					//
440 					// Considering the bug, I think this is acceptable because
441 					// the user can still position themselve right between the
