Conditional expression not working as expected when using OR logic

Terraform Version

Terraform v1.3.7

# Example distilled to its simplest form
variable "test" {
  type = list(string)
  default = null
}

locals {
  myvar = var.test == null || length(var.test) == 0 ? ["no value"] : var.test
}

Debug Output

❯ terraform plan
╷
│ Error: Invalid function argument
│ 
│   on main.tf line 8, in locals:
│    8:   myvar = var.test == null || length(var.test) == 0 ? ["no value"] : var.test
│     ├────────────────
│     │ while calling length(value)
│     │ var.test is null
│ 
│ Invalid value for "value" parameter: argument must not be null.

Expected Behavior

After evaluating var.test == null is true the or is satisfied so myvar should be set to ["no value"]

Actual Behavior

Tries to evaluate length on a null object unnecessarily.

Steps to Reproduce

1. terraform plan

Additional Context

After evaluating the first condition the OR is satisfied, no need to evaluate the other conditions. There are workarounds but this format should work.
