In the above screen Deposit box is not expanded in full.

Steps to reproduce:

• Open Deposit box
• Fill some valid value and client Deposit button
• While its opening MetaMask screen, click on "X" button of Deposit screen and again click on "Deposit" button.
• You would see not fully stretched Deposit box

I changed the behavior so that only a currently pending action would respond to success/failure
