[Bug]: inputImage.size() not working in merge and combine custom glsl nodes

What happened?

While writing custom glsl(gto) nodes I noticed a weird behaviour when trying to access the size of the input images. With the color type it works without Problems.

But with the merge and combine custom nodes inputImage.size() just returns an empty vector (vec2(0,0).

According to the docs

Here is a small file where this is obvious. (When working the resulting image should be shifted to the left, with combine and merge, nothing happens.)

TestColor : IPNodeDefinition (1)
{
    node
    {
        string evaluationType = "color"
        string defaultName = "TestColor"
    }

    function
    {
        string glsl = "vec4 main(const in inputImage in0) {return in0(vec2(in0.size().x/2, 0));}"
    }
}

TestMerge : IPNodeDefinition (1)
{
    node
    {
        string evaluationType = "merge"
        string defaultName = "TestMerge"
    }

    function
    {
        string glsl = "vec4 main(const in inputImage in0, const in inputImage in1) {return in0(vec2(in0.size().x/2, 0));}"
    }
}

TestCombine : IPNodeDefinition (1)
{
    node
    {
        string evaluationType = "combine"
        string defaultName = "TestCombine"
    }

    function
    {

        string glsl = "vec4 main(const in inputImage in0, const in inputImage in1) {return in0(vec2(in0.size().x/2, 0));}"
    }

    parameters
    {
        string layer0 = ""
        string layer1 = ""
    }
}

Additional Info: I only noticed this issue, because those nodetypes (combine & merge) also behave very weird with anamorphic inputs, this might be a topic for another issue, but during the workaround I wanted to get the size, and realized it's not working.

List all the operating systems versions where this is happening

macOS14, LinuxCentos7

On what computer hardware is this happening?

PC, Macbook
