Do not render crossing=unmarked as a zebra

[lionkmp]

Hi all,

First, thank you for the nice OSM tiles!

I've added many unmarked crossings to indicate curb accessibility for wheelchair / blind users. Main tags are like:

highway=crossing
crossing=unmarked
kerb=*
tactile_paving=*

These are locations where pedestrians can cross the streets (Mainly between sidewalk ends on the corner. Or from/to sidewalks from the street.), but they are not painted zebra lines. Still, on OSM France style, they appear as a zebra (attached image, these are small streets with no zebra painting).

I think they should not appear at all on a general map.

crossing values: "marked", "ucontrolled", and "traffic_signals" could appear as a zebra.

Thank you.
