select: clicking the main container doesn't close the menu

Nobody has claimed this yet.

### What is affected?

Component

### Description

First click on the main body opens the menu for a choice as expected,
but clicking the main body again (with the intention of cancellation) is not closing the menu.

### Workaround

a click event listener can be used to manually close the menu when it's opened

### Is this a regression?

No or unsure. This never worked, or I haven't tried before.

### Affected versions

1.0.1

### Browser/OS/Node environment

Everywhere

Reproduce the behavior using the linked playground, starting with the md-outlined-select and md-select-option imports in material-imports.js and index.html. Trace the select component's click handling and identify the existing behavior around reopening an open menu. Done means clicking the main container a second time closes the menu, with a regression check covering that interaction.
