// This test shows a frame with four focusable components: b0, b1, b2, b3.

// Then it presses Tab three times. EDT is freezed for a while on the first FOCUS_LOST event.

// Meantime, the test clicks in a component of another frame and then clicks in the title

// of the original frame. When EDT awakes and all the queued events get processed,

// the other frame should ones gain focus and then pass it to the original frame.

// The b3 component of the orinial frame should finally become a focus owner.

// The FOCUS_LOST/FOCUS_GAINED events order in the original frame is tracked and should be:

// b0 -> b1 -> b2 -> b3.
