Qml TextEdit inside SplitView blanks during editing

Steps to reproduce:
1., unzip the attachment & build & run
2., select the right bottom TextEdit and keep pressing one character for at least 5 secs
Result: after a while the SplitView becomes invisible, buy clicking on left bottom text edit and typing there makes it visible again
Expected Result: SplitView and its content is visible

Workaround: If the text edit is placed inside of a flicker and onCursorRectangleChanged: flick.ensureVisible(cursorRectangle) is used, then it remains visible.
