in JIRA, on Internet Explorer 8, code macro IFRAME bottom scrollbar hides its own contents

Problem Description:
Using:
Jira v4.4#649-r158309
IE 8.0.6001
Firefox 8b

Problem:
Writing a long line of code in between the "code" markups, example:

SELECT 'MAX(_original.._value)' FROM 'testValue_0001.val' TIMERANGE("2011.11.03 11:00:00","2011.11.03 11:16:08",1,0)

On Internet Explorer the line is fully hidden by the scrollbar: one needs to expand the window width in order to remove the scrollbar.

It works fine with Firefox.

It works fine with Chrome on Linux too.
