Can’t create 1×1 triggers with trigger tool

Affected Ved versions: β4, β5, β6
Operating System: Linux Mint Rosa 17.3
LÖVE version: 0.10.0

I can’t create 1×1 triggers with the trigger tool (I call them triggers because calling them script boxes is for dumbasses). I can create the trigger, then edit its p1 and p2 properties to be 1×1, but that is inconvenient.
