FormItem style text-align:left does not work anymore

Steps to reproduce:
1. Create this main MXML:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

<mx:Style>
FormItem

</mx:Style>

<mx:Form>
<mx:FormItem label="First Label">
<mx:TextInput />
</mx:FormItem>
<mx:FormItem label="Another Label">
<mx:TextInput />
</mx:FormItem>
</mx:Form>

</mx:Application>

2. Compile & Lauch

Actual Results: FormItem labels are aligned right

Expected Results: FormItem labels are aligned left

Comment: This worked in the previous releases but has seemed to change lately

Workaround (if any):
Apply styles to the FormItemLabel class, not FormItem.

<mx:Style>
FormItemLabel

</mx:Style>
