Projectile spell fireballs not activating on entities with fire resistance

[Eroil]

When shooting a projectile spell as a fireball (all sizes) at a player or mob with fire resistance, the spell doesn't activate most of the time. I assume this is because of the vanilla mechanic where ghast fireballs don't affect entities with fire resistance. If possible to make it so it detects the cancel event and still casts the spell could be a great fix.
