Base Model filter not applied when navigating with “Next Model” / “Previous Model” in Model Browser

[AnbaiMei]

What happened?

The Base Model filter in the Model Browser does not remain applied when using the “Next Model” or “Previous Model” buttons on the model detail page.

Steps to reproduce

1. In the Model Browser, set the following filters:
   • Search term: @freckledvixon
   • Sort: Newest
   • Period: AllTime
   • Model Type: All
   • Base Model: Pony
2. Click on any model from the filtered results.
   • The initially opened model is correctly filtered to a Pony base model.
3. On the model detail page, click “Next Model” or “Previous Model”.

Expected behavior

Only models that match the selected Base Model (Pony) should appear when navigating between models.

Actual behavior

After clicking “Next Model” or “Previous Model”, the Base Model filter appears to be ignored — models with other base types such as “Illustrious” or “SD 1.5” are also shown.
Even when navigating back to a previously filtered model using “Previous Model”, the filter remains inactive and non-Pony models continue to appear.
