Method nsIRange::setEnd() has the same behaviour. Specs says: "The start position of a Range is guaranteed to never be after the end position. To enforce this restriction, if the start is set to be at a position after the end, the Range is collapsed to that position. Similarly, if the end is set to be at a position before the start, the Range is collapsed to that position." http://lxr.mozilla.org/mozilla/source/content/base/src/nsRange.cpp nsIRange::setStart() 965 // the start must be before the end 966 if (!IsIncreasing(aParent, aOffset, mEndParent, mEndOffset)) { 967 return NS_ERROR_ILLEGAL_VALUE; 968 } nsIRange::setEnd() 1018 // start must be before end 1019 if (mIsPositioned && !IsIncreasing(mStartParent,mStartOffset,theParent,aOffset)) 1020 return NS_ERROR_ILLEGAL_VALUE;.
