IE TextRange选择方法无法正常工作

I'm having an unusual problem with an IE document with contentEditable set to true. Calling select() on a range that is positioned at the end of a text node that immediately precedes a block element causes the selection to be shifted to the right one character and appear where it shouldn't. I've submitted a bug to Microsoft against IE8. If you can, please vote for this issue so that it can be fixed.I'm having an unusual problem with an IE docume
