Mac: Text is selected in QTextEdit/QWebView when window with it is opened and mouse cursor is moved in.

Steps to reproduce:

Compile and run "windowflags" example.
Close "Preview" window.
Select widget type in controller window - preview will open.
Move mouse (relatevely fast) into preview window.
Text in QTextEdit will be selected.

If you set event filter for textEdit, it will show that it receives tons of QEvent::InputMethodQuery events.

In similar case with QWebView, webview receives QEvent::Enter, QEvent::MouseMove, and QEvent::MouseButtonPress (when no button were actually pressed), and therefore "thinks" that mouse button is pressed and hold, as no QEvent::MouseButtonRelease is received.
