Describe the bug
/tracemask doesn't seem to do anything, using /tracemask #solid will still stop the raytracer at water, /tracemask air and /tracemask water will do the same thing.

To Reproduce

1. /brush sphere air 3
2. /tracemask #solid or /tracemask air or /tracemask water
3. Click on water with ground underneath
   The water will be removed.

Expected behavior
The ground under the water is removed.

Additional context
Running Paper 118 on Minecraft 1.15.2
Running worldedit-bukkit-7.1.0.jar and AsyncWorldEdit-3.6.16.jar.

Okay, only after typing this issue I realised AsyncWorldEdit may have something to do with it but I already disabled with their built in feature, but then it still didn't work. Only after actually removing it from the server completely did it start working again. Guess I have to send them a bug report.
