Utils: Fix StyleHelper::drawArrow workaround for 6.4.0

Browse Source 
The workaround that fixed the drawing of arrows after a change between
6.4.0 and 6.4.1 broke the drawing of arrows with Qt 6.4.0.

This change add another enforced detachment of the palette (leading to a
modified cache key) that works with Qt 6.4.0. It still works with 6.4.1.
