title: Do mouse clicks bring keyboard focus to focusable controls by default?
body: <p>This question can seem quite odd but from all my experience I've gotten used to setting keyboard focus to the focusable element just by clicking it with the mouse; however, UserControl with the properties <code>Focusable = true</code> and <code>IsTabStop = true</code> came as a surprise to me because it gets keyboard focus via Tab but stays ignorant to mouse clicks.</p>
