Flex embedded fonts cause tab characters to be stripped

Question

I'm trying to paste text into a flex textarea. The text I'm pasting has newlines and tabs, but when I paste the text into the textarea, the tabs are stripped out.

If I comment out the CSS line font-family: EmbArial; the tabs will be preserved. I tried using different font files, but it didn't help.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Style>
        Application
        {
            /*font-family: EmbArial; /*remove comment to show problem*/
        }
        @font-face
        {
            font-family: "EmbArial";
            src: url("fonts/BKANT.TTF");
        }
    </mx:Style>
    <mx:TextArea id="textStuff" width="300" height="100" text="Paste stuff with tabs!"/>
</mx:Application>
