Qt 5.6.1 - MouseArea pressed() and onPressAndHold() misbihaving - BUG?

[Szymon]

Qt Version 5.6.1
Device: WEC7
When I run the example below on WEC7 the MouseArea signals misbehave.
I press and hold the close button.
I get the following flow of the signals:
Status:+pressed+pressandhold+released+pressed+pressandhold+released

When I run this example on Win32 i get the expected behaviour:
Status:+pressed+pressandhold+released

So I guess either there is a BUG in WINCE/WEC or I am something missing here.
"+pressandhold+released" signals get emitted almost immediattely after the press.
Could anyone help? Any ideas?
