Current Behavior

Given a drawer or dialog that has an input with autoFocus={true}, and a focusable element preceding the input:

1. Open the dialog.
2. The first focusable element in the dialog is focused.

Expected Behavior

Given a drawer or dialog that has an input with autoFocus={true}, and a focusable element preceding the input:

1. Open the dialog.
2. The input with autoFocus={true} in the dialog is focused.
