Bug 950225 - Prevent the click event pass the under panel.

Hi Gareth,

We do workaround here.
Because the click event just pass through the "create-account-view" panel to the under panel
with unknown reasons, then the bug is happened.
It might be a Gecko issue.

If we want to fix the issue without any workaround, we might fix it in Gecko not in Gaia.
Please give me feedback for this.
Thanks.
