Returned (inner)width and (inner) height are incorrect in FF & IE

[Motty]

When getting width, innerWidth, height or innerHeight on an element with a border (5px in this example) the returned value is incorrect (​http://jsfiddle.net/Zs92Q/1/):

Border Size	0		5px
Firefox	Width	50	49.83333999999999
	Height	50	49.83333999999999
Chrome	Width	50	50
	Height	50	50
Opera	Width	50	50
	Height	50	50
Safari	Width	50	50
	Height	50	50
IE7	Width	50	49
	Height	50	49
IE8	Width	50	49
	Height	50	49
IE9	Width	50	50.019999999999996
	Height	50	50.019999999999996

It appears that jQuery v1.3.2 was the last version that returned the correct value of "50".

Maybe I should have specified that the data I collected is for the Windows versions? I'm not sure why this ticket was closed... Here is my screenshot from Firefox
