`number | vector` type errors on multiplication with `number`

[nnullcolumn]

local a: number
local b: vector
local c: number | vector

-- number * vector / vector * number fine
print(a * b, b * a)


-- i would expect this not to type error:
--   Expected this to be 'number', but got 'number | vector'; 
--   `vector` is not a subtype of `number`
print(c * a, a * c)

-- no type error on 'number | vector' * 'vector'
print(c * b, b * c)
