Expected behavior

When viewing a product grid filtered by a tag, there will sometimes be products visible in that tag that don't belong.

Actual Behavior

Sometimes products show up on tag pages that should not be there

Steps to Reproduce the Behavior

With a fresh install

1. Add a new product ( add title, update variants, etc)
2. Publish
3. Edit product and add a new tag
4. Add tag to navbar
5. observe that on shop / ( there are products that don't belong )

This doesn't always happen, and with some fiddling, you can fix it by juggling tags on products that are showing up incorrectly.
