The Header Row of a TableView uses the Background Color of the TableView since 3.21.6

[Claus Dietrich <claus.dietrich@xxxxxxxxxx>]

One guy in our German Gambas Club claimed that in Gambas 3.21.6 the 
header row now changes its color with the background color property of 
the TableView.

So I set the background color of a TableView to orange and found, that 
the background color of the header row also changed its background color 
to orange. It's just a bit darker than the rest on the table.

In a counter test with Gambas 3.21.4 the background color of the header 
row did not change to orange. It showed a complete different color.

Is that by new design or a bug or do we have to deal with a new feature?

It happens with QT5, QT6 and GTK+3.

Best regards
