Description
#### Bug, feature request, or proposal:
The animation for sliding in mat-sidenav (in `over` mode) on Chrome (latest) on older Android phones (reproducible on Xperia M5 E6633 with Android 6.0.0) is very choppy and slow
#### What is the expected behavior?
Animation should be smooth. Other sidenav libraries (at least those which use transform) are smooth.
#### What is the current behavior?
Choppy animation
#### What are the steps to reproduce?
A new project with Angular 6 and `ng add ... sidenav-stuff ...`
#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Angular, Material 6, TS 2.7.2, Chrome Android 66.0.3359.158
Contributor guide
Research direction
Reproduce the issue in a new Angular 6 project using mat-sidenav in over mode on Chrome for Android, preferably with the reported Xperia M5 environment. Start by examining the mat-sidenav animation path and compare its behavior with transform-based implementations. Done means the sidenav animation is smooth on the reported older Android device without regressing other modes.
