This is a minor usability bug, and there may or may not be a dependency on MnM Mobile Styles: We noticed that when we have a pre-filled MnM variable / variation product that starts fully-loaded, e.g. 20/20 products pre-filled, if we click on a zero-quantity item, overflow is allowed, e.g. 21/20 products in the MnM container (and that overflow is displayed in the Mobile Styles footer).
Clicking on other zero-quantity items will continue to overflow the container., e.g. 22/20, 23/20, etc
Fortunately, Add to Cart button in the Mobile Styles footer is blocked/greyed-out while the overflow state is active.
Note that this overflow is not allowed/possible in regular (non-variable) MnM products.
