Describe the bug

As mentioned in this comment, When Inherit query from template is active, keyword filter still works.

Screen.Recording.2023-03-24.at.2.16.36.PM.mov

To reproduce

1. Edit the Product Search Results template.
2. Add the Products block.
3. Add a Keyword filter. Once a keyword is added, the editor will display products that are filtered by the keyword.
4. Enable Inherit query from template.
5. You will see that the products in the editor are still filtered by the keyword.

Expected behavior

When Inherit query from template is enabled, we should see products based on current template i.e. keyword filter shouldn't have any effect on the products showing in Editor & Frontend.
