Testcase - `user-select: none;` blocks clear selection
In Chrome and Safari, clicking/tapping on elements that have `user-select: none;` do not clear selections within other elements.
On this page, all elements have `user-select: none;` except for these `.message` boxes. You can select this text. But to clear the selection, you can not click or tap anywhere on the document except a `.message` box.
Firefox behaves as expected, and lets you clear any selection by tapping anywhere.
