[BlackBerry] VKB flickers in and out when tapping on webview after text selection on URL bar

• Component: WebKit BlackBerry
• Status: RESOLVED FIXED

[Sean Wang]

RIM Bug:245678
Steps:

1) Launch browser and navigate to a site
2) Tap on the URL bar so that the text is highlighted.
3) Press and hold the URL bar.
4) Tap on the webcontent to dismiss selection and CCM

Actual:

3) The VKB is dismissed and the CCM is displayed on the side.
4) You would see the VKB flicker in and out.


Expected:

3) The VKB is dismissed and the CCM is displayed on the side.
4) The text selection on the URL bar is dismissed and the CCM disappears.

There is a function "void FrameView::performPostLayoutTasks()" which will call FrameSelection::updateAppearance() on every time the FrameView layout is finished. So I think the selection changing will be notified at last.

If we don't ensure it, another solution is to check and layoutIfNeeded at the beginning of "SelectionHandler::selectionPositionChanged()".
