    Properties / styling panels build their controls into a plain
    QVBoxLayout, so when the dock or dialog is dragged below the content's
    natural size Qt squeezes the children (zero-width combos, clipped
    labels). Wrapping the content in a frameless, resizable QScrollArea
    lets the content hold its minimum size and scroll instead — matching
    layerstylingdock.cpp and swmm2dresultsstylepanel.cpp, which already
    do this. One helper, reused, rather than re-deriving the lambda.
