usePassThrough: Components with function as their value doesn't seem to work properly

[firlottea]

Describe the bug

const CustomTailwindTheme = usePassThrough(
  Tailwind,
  {
    datatable: {
      column: {
        //  Attempt 1:
        // headercell: ({ context, props }) => ({
        //   class: ['!px-4 !pt-2 !pb-0 bg-pink-500'],
        // }),
        //  Attempt 2:
        // headercell: ({ context, props }) => ({
        //   class: '!px-4 !pt-2 !pb-0 bg-pink-500',
        // }),
        //  Attempt 3:
        // headercell: {
        //   class: ['!px-4 !pt-2 !pb-0 bg-pink-500'],
        // },
        //  Attempt 4:
        headercell: {
          class: '!px-4 !pt-2 !pb-0 bg-pink-500',
        },
        columnfilter: {
          class: ['!pb-2 bg-pink-500'],
        },
      },
    },
    paginator: {
      rowperpagedropdown: {
        root: {
          class: ['md:!w-24'],
        },
      },
    },
  },
  { merge: true, useMergeProps: true }
);

When trying to have global PassThrough on component which have a function as their value
EX :

headercell: function headercell(_ref162) {

Seems like there is no way to merge the Global classes and the ones provided by the Tailwind PassThrough class.

Attempt 1 :
The class property is empty

Attempt 2 :
The class property is empty

Attempt 3 :
The class property is overwritten by the pt2 value

Attempt 4 :
The class property is overwritten by the pt2 value

I tried with useMergeProps at true and false.

https://stackblitz.com/edit/t2cmve?file=src%2Fmain.js

PrimeVue version

3.32

Vue version

3.x

Language

ES6

Build / Runtime

Vite

Browser(s)

Firefox Developper Edition

Steps to reproduce the behavior

1. Open the provided Stackblitz link
2. Inspect the class property of the "headercell"
3. Comment or uncomment each headercell attempt in the main.js file
4. Inspect the class property of the "headercell"

Expected behavior

Classes from usePassThrough should be merged and not overwritten. Also the syntaxed shown in the panel.header section here
https://primevue.org/tailwind/#customization
doesn't seem like it's working for this Component. (Haven't tried many other components)
