Android, backspace doesn't work in a flash.text.TextField, spark TextInput or spark TextArea

Hello,

I have a strange bug on my Nexus 5 Android 4.4 Air 3.9.
In a flash.text.TextField, a spark TextInput or a spark TextArea that uses "spark.skins.mobile.TextInputSkin" or "spark.skins.mobile.TextAreaSkin", when I select the textField (a long press -> the cursor appear at the first position), the backspace doesn't work.

I'd like to ask everyone affected by this issue to take a minute and vote for the following bug. It currently has zero votes:
