Description
Hi, I've got a small problem with overlapping tiles and white "blank" spaces, there might be a flag option I'm missing that would fix this issue.
When I run plain tippecanoe command, without and additional flags except "-z14" and "-pk" , I get this:
When I run "tippecanoe -z14 -D8 -aL -b10 -o file.mbtiles --force" , I get much better results but overlaps appear and some blank spaces are transformed into polygons :
I have tried "-ab", "-g2", "-pc", "-pD" flags but without luck since it gives same or worse results.
Also, is it possible to automatically interpolate blank spaces with same values that surrounding features have?
Thanks a world!

Research direction
Start by reproducing the two command lines in the issue, comparing the plain -z14 -pk run with the -D8 -aL -b10 run and the other flags tried. Investigate the resulting tile gaps, overlaps, and polygons; done should include a confirmed cause and a documented fix or clear determination of whether blank-space interpolation is supported.
