Monster spellcasting doesn't respect obstacles as it should

Describe the bug

Monsters are able to aim and cast blast spells through impassable obstacles, but aren't able to cast NO_PROJECTILE spells through (transparent) walls.

Steps to reproduce

Paste the spell+monster combo from Additional Context
Start a game in the evac shelter, open a blind and (optionally) kill the starting NPC to test in peace
Spawn Blasto on the other side of the window and behold your shelter getting filled by lightning
Kill Blasto and spawn Zappo, watch his supposedly wall-ignoring zaps failing to penetrate the window

Expected behavior

Blast spells stopping at impassable obstacles unless otherwise specified, wall-penetrating spells penetrating walls as advertised. You can't even game the system with tacking the blast spell onto the line spell as an extra effect since extras are cast from the caster's position near as I can tell.
