aria-* attributes do not match their roles

[ventralnet]

Hello, I am currently performing accessibility testing for my application. The first step we are doing is running chrome dev tools light house to test our app generally.

It looks like days in the date picker are assigned the role of gridcell. They also have an aria-* rolled defined which I assume is storing the 'pressed' state (aria-pressed="true|false")

This flags as an issue because the mismatch is not to spec/is not a attribute valid for gridcell roles
