Windows 10/Vista style: QLineEdit ignores QPalette::Base color role if it is added as a widget to QGraphicsView

On Windows 10 if a widget has palette set with QPalette::Base color changed, that color is ignored if the Widget is added to a graphics view's scene by addWidget().

On Windows 7 this works as expected. Also if we don't use the QGraphicsView, the palette color works as it should.

Steps to reproduce:

• Run attached sample
• Observe the QTextEdit background color
• EXPECTED: Background color is green
• ACTUAL: Background color is white - any color is ignored
