Hi,
This is an in-progress Polaris IndexTable product page in my Shopify app extension (built with the remix template):
In each row, I have a primary data link to the shopify:admin/products/<id> product details page, which works great:
Once the embedded admin product details page opens, the included back button...

...returns to my IndexTable page as expected. However, the issue is that the back button URL is missing my search-params.
I use search-params for the selected filter tab, pagination and sorting. Just like the Shopify admin product page itself. Notice the search-params in the URL of the Shopify version of this page:

And you can see that the same search params are in the admin back button's url, via the browser's hover status line:

So of course, when you click the back button, it returns you to the list of products in the same selected-tab-filter/pagination/sorting state as before.
However, in my app, you can see that the Shopify admin back button's URL has been stripped of search params:

On the other hand, the browser back button works correctly. It goes back to my page, with the search-params for my page included.
As the embedded Shopify admin product details page is not in my control, I can't think of a way to fix this from my side. At least not without doing some ugly work-arounds.
Please advise if this is a bug, or if I'm missing something.
Thanks!
