We no longer need it since Rect 16 takes care of passing the context around.
It's also deprecated: https://atlaskit.atlassian.com/packages/core/layer-manager

That standalone ButtonGroup package has been deprecated.
The deprecation warning says to use the ButtonGroup component
from the Button package.

Prepare for React 16.

If there is no focused node inside the dialog we focus any of the available buttons, submit button is first.

Some atlaskit components, such as field-text, inherit text color.
This is a problem with components that are white as they will
inherit $defaultColor, which is a light gray. So instead, for
the atlaskit modal, set a color for all the form content so it
can be inherited instead.

Dialog does not currently support displaying dynamic strings
for titles, only static strings listed for translation. Accept
a new prop that explicitly states it is for setting the title
and have the web dialog prefer it over the titleKey.

Atlaskit at times will have localized styling for font-size and
sometimes will not. The button component will inherit its
font-size whereas selectors have localized font-size of 14px. For
consistency, the cancel/submit buttons on the atlaskit modals
will also have 14px. The atlaskit story book examples also use
buttons with 14px font-size.
