mapcss: grouping doesn't work correctly

[Klumbumbus]

For example see ​way/4592789
I want to hide the new cycleway mappaint of elemstyle (see #10057). So I use an additional mapcss file with the following code. This work fine and hides all cycleway tracks.

way.tR::core_cycleway
{
        width: 0;
}
way[prop("tL","core_cycleway")]::core_cycleway2
{
        width: 0;
}

However, grouping both selectors as in the following example doesn't work correctly.

way.tR::core_cycleway,
way[prop("tL","core_cycleway")]::core_cycleway2
{
        width: 0;
}

With this code there is still a track at one side of the highway. It is even not always the same side. Manually reloading the style severaltimes successively in the mappaint dialog results in showing sometimes the left track and sometimes the right track.

See #8568.

Maybe we should just revert [6736]. Comma is not a logical or, but a shortcut for multiple identical declaration blocks (​http://www.w3.org/TR/selectors/#grouping).
