The ~= operator is a Qt Stylesheet thing that let's Qt stylesheets act
like HTML CSS with classes. So having a class is probably the most
fundamental selector in CSS, ignoring ID, but it's a second class
citizen in Qt Stylesheets, implemented by ~= which is "attribute
contains". So
HTML CSS
p.foo { }
Qt Stylesheet
p[style_class ~= 'foo'] { }
where style_class is arbitrary, but what Leo uses.
But I'd take second class citizen over broken, which is what I think it
is in Qt >= 5.8, unless it got fixed and they never cleared the bug
report.
