They would render as land previously but starting some time ago, the assumption was changed that they are actually sea with some islands in it. So tiles that had been "mistagged" like that would work before and have been broken afterwards. At least that is my theory.
I was doing some edits and started to wonder, is there really any need
to flag tiles as mixed sea/land tiles? Couldn't we just have sea and
land tiles and nothing in between. Someone has to draw the coastline for
mixed tiles anyway and when the coastline is there, the empty tile
database for that tile is redundant information anyway.
