Symbian: Button is shown pressed when the finger is slided outside of the button area

Button is shown pressed when the finger is slided outside of the button area

Preconditions:

You have N97 or other Symbian device with Qt 4.6.3

Steps:

1) Create a QtWebKit showing a web page with button, shown inside scrollbar area
2) touch scrollbar
3) press button down, move finger outside of the button and release the finger.
-> now the button is shown still as "pressed" instead of being shown as normal, "released"

Test application as attached (testwebkit.zip), where there is a gray rectangle with black borders. When the user presses the button, it changes to white rectangle with green borders. When the user moves the finger out of the button region, the button is still shown as pressed.

It can be that this bug is inside Qt, probably in QS60Style, since I have heard that some are experiencing it also without the QtWebKit. I shortly tested similar settings without the QtWebKit and did not receive errors, though. For my test set, see the testbutton.zip included.
