## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Select has logic in place to prevent the overlay from opening when
clicking the slotted content. As part of this, we need to deal with the
`<label>` element dispatching another click that then bubbles up and
causes the overlay to open when clicking the slotted content. We
currently deal with this by calling `preventDefault` which prevents this
extra event from being dispatched only when clicking the slotted
content.

We also call `stopPropagation`. This code is not necessary, and in most
cases should not have any adverse effects on developer applications.
However, this does impact React applications due to how React handles
events. When a developer places `onClick` on a slotted element, a native
"click" listener is not immediately applied to that element. Instead,
React adds a native "click" listener to the root element of an
application. When that listener's callback fires, React will dispatch a
synthetic click event on the slotted element. Since we are calling
`stopPropagation`, the click event never bubbles up to this root node's
listener. As a result, the synthetic event is never dispatched on the
slotted element, and the developed `onClick` callback never fires.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Select no longer prevents events from bubbling. The existing
`event.preventDefault` is sufficient to prevent the label from
dispatching another click (thereby causing the select overlay to open)
when clicking the slotted content.
