Controller: L2 won't work, and missing the tiny + and - buttons causes accidental purchase

[sam686]

Using Dualshock 4 controller from PS4, and using Steam's controller support.

L2 button doesn't work correctly, and the cursor not quite on top of the tiny buttons of "+" and "-" causes accidental purchase when repeatedly pressing "X" button to add or subtract a few of them. Purchase with the "X" button (PS4 controller) need to be changed to ONLY work when the cursor is on the "Purchase".

The pop up message did not give enough time to read it while repeatedly pressing the "X" button. The "X" button on controller wants to purchase no matter where the cursor is.

I am probably going to remap the menu "X" button to a mouse down button in steam controller configuration, because of this lame accidental purchase problem, to reduce this pop up problem not looking at where the cursor is.
