Steps:
- I have a configurable product with main image for thumbnail and everything else.
- I create a variation with it's own image.
- I select hidden in product page in the main product's image.
- Placerholder is shown.
- I select a color and now the image is shown.
- Problem: the gallery shows two items, one being the placeholder. Why is this the expected behabior? Makes no sense to show the place holder in the gallery.
How can I remove the placeholder an only leave the simple products images?
I have my own custom theme with some very little edits of luma.
