Rendering of menus doesn't look right

[nparkanyi]

• The little blue highlight bar is missing on the selected menu
• Poor contrast on the submenu arrow
• The selection rectangle seems to spill outside the boundary a bit

With this:

--- a/src/style/adwaitastyle.cpp
+++ b/src/style/adwaitastyle.cpp
@@ -4932,7 +4932,7 @@ bool Style::drawMenuBarItemControl(const QStyleOption *option, QPainter *painter
     if (useStrongFocus && sunken) {
         StyleOptions styleOptions(painter, QRect(rect.left(), rect.bottom() - 2, rect.width(), 3));
         styleOptions.setColorVariant(_variant);
-        styleOptions.setOutlineColor(Colors::focusColor(StyleOptions(palette, _variant)));
+               styleOptions.setColor(Colors::focusColor(StyleOptions(palette, _variant)));
         Adwaita::Renderer::renderFocusRect(styleOptions);
     }

the highlight rectangle shows up (though it's not the right shade of blue).

Fixed with #179.
