Cartographers time out server when searching for structures

When trading with cartographers the server will time out while searching through chunks to get structures for the maps. On my server this occurred when the woodland mansion map trade was unlocked, possibly because a woodland mansion could not be found. The stack was logged on a paper server, but the same bug happens on a vanilla server. The stack trace is as follows:
