Table width problem

Hi!

When i create table and set table width to "500" CKEditor put it in to style tag:

<table border="1" cellpadding="1" cellspacing="1" height="80" style="width: 500px;">

But if i resize the table by mouse (drag and drop right border), CKEditor change table width this way (in width tag):

<table border="1" cellpadding="1" cellspacing="1" height="80" width="582">

And this new value can't be changed in "Table Properties" dialog - if i want to set 90% here, the only way is to edit html code :(

Is there any way to set up CKEditor to put table width to same tag every time ?

P.S. I've check it on last version CKEditor  in demo page here
