Vanished-players-don-t-have-rights patch incomplete

[kennytv]

Steps/models to reproduce:

(using 1.14 paper-66, not sure if that's a thing in 1.13)
Hide player A from player B -> player B can't place blocks in player A's position, even though A is invisible.

The patch 0264-Vanished-players-don-t-have-rights.patch does add a canSee boolean to the methods below, but both
in IWorldReader and

in IEntityAccess don't actually make use of them (as seen by the wonderful gray, squiggly line 👀).
