[glsl-in] Validation failure with swizzle + inout argument

[fintelia]

This shader:

#version 450

void foo(inout vec2 p) {}

void main() {
    vec2 bar = vec2(1);
    foo(bar.xy);
}

Produces this error:

  ┌─ swizzle-inout.vert:5:1
  │

  │ ^^^^^^^^^^^ naga::Function [2]
6 │     vec2 bar = vec2(1);

  │            ^^^ naga::Expression [8]

Function [2] 'main' is invalid: 
	The pointer [8] doesn't relate to a valid destination for a store
