onClickOutside: Option to use mousedown event

[anjoseb121]

Clear and concise description of the problem

As a developer using onClickOutside function I want trigger the listener earlier. Common actions such as clicking outside to close, are being prevented from happening when you press down outside to perform another action, such as resizing or drag and drop.
I'm willing to submit a PR for the issue.

Suggested solution

In OnClickOutsideOptions we could have an option to call the listener on the click or mousedown event.

Alternative

Having an onMouseDownOutside function.
