cycle track is auto-filled to cycle lane

[westnordost]

Inputting in https://a-b-street.github.io/osm2lanes/

highway=residential
cycleway=track

auto-fills to

cycleway:both=lane
cycleway:left:oneway=-1
cycleway:right:oneway=yes
highway=residential
lanes=2
lanes:backward=1
lanes:forward=1
shoulder=no
sidewalk=no

Now, where does the cycle lane come from?

the lanes to tags parsing does not yet know how to differentiate a lane from a track, so it defaults to lane:
