IE8 line-height issues

[aaronmuir]

For me line-height wasn't being calculated properly in IE when I didn't specify css line-height for a textarea, so I put the following in to work around it in the future. Also, I switched to "isNaN()" rather than "==NaN"

    if (jQuery.browser.msie && (isNaN(this.line_height))) {
        jQuery(e).css('line-height','100%');
        this.line_height=parseInt(jQuery(e).css('line-height'));
    }
    this.line_height = isNaN(this.line_height)? 0 : this.line_height;
