[3.x]: Post request required in product preview
What happened?
Description
When you preview a product and start navigating away from the current page it throws a "Post request required" error. I understand that a preview is mostly for visualizing the current page but a client had some issues with this.
He wanted to test what the effect of his adjustments are on the display of the variants. These work with colors and size combinations. Selecting one influences the display of other options. The selection uses a link to a different variant: https://mysite.be/nl-be/products/my-product?variant=142089 https://mysite.be/nl-be/products/my-product?variant=142088
So to get this working in preview would be really useful.

Steps to reproduce
- Preview a product
- Click any link in the preview that navigates away from the current page
