Sidebar: Keep headers minimum height on two columns
The implicitHeader
binding from sizeHelper
is getting overriden
by Kirigami.AbstractApplicationHeader
, which recalculates
a preferred height using the header's childrens implicit heights.
What's really keeping the header height at the desired value is the hamburger button, so let's keep that size also when showing two columns
