Issue:
change slide 'in' transform styles to none
<!--- Provide a general summary of the issue in the Title above -->
i was creating a drawer with a drag and drop package [(rbd from Atlassian)](https://github.com/atlassian/react-beautiful-dnd) when I stumbled upon an issue. due to the drawer being fixed to the right, the dragged element is pushed over to the right positioning it off screen. This happens because of the combination of `position: fixed;` and a transform value. For the drawer, actually the slide component, the entered style is `transform: translate(0px, 0px)`. This affect the transform of the dragged element of rbd, as they also position with transform.

## Expected Behavior 🤔
<!---
    Describe what should happen.
-->
The resulting transform value of the slide component should be customizable or should be `none`. changing the values on [these lines](https://github.com/mui-org/material-ui/blob/a52834b02fad29624829320de78841bbef97abaf/packages/material-ui/src/Slide/Slide.js#L129) will fix the described issue.

## Current Behavior 😯
<!---
    Describe what happens instead of the expected behavior.
-->
The resulting transform value of the slide component can not be customized. The hardcoded value is, in some use cases, affecting styling of child components as it has an actual value. This causes the element that's being dragged to be positioned wrong.

What the change will fix is illustrated in https://codesandbox.io/s/ij7ux
The only thing that changes is the value of transform and it will not break the transition.
tested it in latest: chrome, safari and firefox. All have the same issue and behave the same with the fix.

Discussion:
@gijsbotje Could it be a bug with react-beautiful-dnd? The transition is broken in https://codesandbox.io/s/ij7ux.
@oliviertassinari i mentioned below the button in that demo it is broken 😄 
I could try and destruct the drawer and make another demo, though a PR might be the easier way of showing it.
Though the animation is broken `translate(0px, 0px) === none` as it returns to its original transform position.
Would a PR be allright or do you wan't a working demo?
@gijsbotje I have tried the following diff:

But it doesn't work on IE 11 (it does on Chrome, Edge, and Firefox).

What does https://github.com/atlassian/react-beautiful-dnd say about the transform problem?
