building:min_level of building:part is ignored

[kayD]

A building:part that specifies building:min_level is handled as if this attribute is ignored.

Expected behavior
If for example a building:min_level=1 is specified, then the ground level should be empty/not filled.

Example 1
https://www.openstreetmap.org/way/1174378874#map=19/49.78869/9.93246
https://streets.gl/#49.78877,9.93248,45.00,17.57,89.69

The goldenrod building part should only be level 1, level 0 (ground) should not be there.

Example 2
A two-floor building, level 0 should be white, level 1 should be brown.
level 0: https://www.openstreetmap.org/way/1174541749
level 1: https://www.openstreetmap.org/way/1174541748
https://streets.gl/#50.49784,9.94346,45.00,0.00,112.93

The brown top floor is rendered also for the ground floor, conflicting with the white colour.

Additional context
Please note that this seems unrelated to the problem about rendering building outlines when building:part geometry is present, which is handled in #3
I do recall that this worked before, but not 100% sure any more.

I think this bug has been fixed in the meantime by @StrandedKitty: the location mentioned in the original post now looks like this:

Which is the expected rendering!
