Toasts position is broken

[Grmiade]

Bug report

• Package version(s): 2.0-rc3
• Browser and OS versions: Tested on Chrome

Steps to reproduce

1. In docs, select a position
2. And click on buttons to show toasts

Actual behavior

The chosen position seems not be correctly applied. And break the toast style 😱

Expected behavior

The old behavior :) With correct position.

[reiv]

This seems to be a regression introduced in 2d7f756.

Specifically, a <div> that previously existed as a child of .pt-toast-container and parent of .pt-toast is no longer rendered as a result of that commit, and its styles are now applied directly to the .pt-toast <div>:

blueprint/packages/core/src/components/toast/_toast.scss

Lines 161 to 170 in 0fe776f

	// TransitionGroup
	> div {
	display: flex;
	flex-direction: column;
	align-items: center;
	// prevent container from scrolling as new toasts enter (from bottom)
	overflow: hidden;
	// ensure there's enough space for full box-shadow
	padding: 0 $toast-margin $toast-margin;
	}
