Unknownreported this bug
Summary
When attempting to use the effect "blockmask" on an entity using the @self targeter, it only transforms blocks that are non-transparent whilst transparent blocks like glass remain unaffected. Messages in the official discord indicate this also happens with the @forward targeter.
Steps to reproduce
Use below effect on zombie. effect:blockmask{m=ice;d=60;r=2;n=2} @self
Current behavior
Only transforms solid blocks, transparent blocks remain unaffected.
Intended correct behavior
Should affect all blocks with some creative only blocks being exempt.
