Opening Modals adds padding to right of components

[jpung]

• [x ] I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

Opening a modal should not add any padding anywhere

Current Behavior

When i open a select or a modal < overflow: hidden; padding-right: 15px> is suddenly added to the div styles as a hardcoded style

Steps to Reproduce (for bugs)

Opening any modals or select dropdowns trigger the issue. I've checked and its even happening on the material-ui-next site.

Context

Just occured today, it was fine and then all of sudden the right side started messing up, i got this random white column next to my scrollbar(ive gotten rid of it) and then i realized the padding issue
