Fix T92791: collapsed nodes scaling widget wrong with interface scale

Size, position and scale of the "two-line" widget (the one to scale a
node horizontally) was not taking interface scale into account. In the
case of the report, it could happen it draws behind an output socket.

before (at 2.0 interface scale)
{F11698493}

after (at 2.0 interface scale)
{F11698501}
