Expected Behaviour

---@class a
local a = {}

---@class b
local b = {}

---@type a[]
local c = {
    a,
    b, // assign-type-mismatch emitted here
}
c = "" // assign-type-mismatch emitted here
c = b // assign-type-mismatch emitted here
c = a // assign-type-mismatch emitted here

Actual Behaviour

---@class a
local a = {}

---@class b
local b = {}

---@type a[]
local c = {
    a,
    b, // assign-type-mismatch is correctly emitted here
}
c = "" // assign-type-mismatch is correctly emitted here
c = b // No assign-type-mismatch is emitted here.  I would expect it to be emitted here.
c = a // No assign-type-mismatch is emitted here.  I would expect it to be emitted here.

Reproduce el informe utilizando el .luarc.json y el fragmento de Lua proporcionados, comprobando los tres casos de asignación que implican la anotación a[]. Sigue la ruta de comprobación de tipos responsable de los diagnósticos assign-type-mismatch y compara las asignaciones de clases con la asignación de string y el elemento del literal de array, que ya se diagnostican. Se considera terminado cuando las asignaciones de clases incompatibles al array se diagnostiquen sin cambiar los diagnósticos existentes.
