The preview image for the Texture Sample Node does not update when the Texture parameter is linked to a Texture Object.
Tested in 4.21.2 (CL - 4753647), 4.22 (CL - 5365847), 4.23(CL - 5396611)
Expected: The Texture Sample Preview image would reflect the same texture value of the Texture Object
Result: The Texture Sample does not update
