#741 Window.setMode("modal") shall not suspend even in listener
The follow code snippet will generate half-baked window if it is created in an event listener -- for example, you can test it by copying it to zkdemo's Try. It is because setMode("modal") actually calls doModal(), and doModal() suspends the execution.
It is better to always post an event to become a modal window later for this case.
Codes:
<window mode="modal" width="200px">
test
</window>

Note:
* <p>Notice: though both setMode("modal") and doModal() both
* causes the window to become modal, they are a bit different.
* doModal causes the event listener to suspend immediately,
* while setMode("modal") posts an event ({@link Events#ON_MODAL}).
* That is, {@link #setMode} won't suspend the execution immediately,
* but {@link #doModal} will.
* {@link #doModal} can be called only in an event listener,
* while {@link #setMode} can be called anytime.
