Back Arrows Returning to Previous Spot on Display Page

Site URL: https://someguystop1000albums.com

So I have a site that is thumbnail gallery display pages where each thumbnail links to its own post. I have 1000 of these broken into 10 display pages that are accessed from the navigation.

Recently I switched from Avenue to Brine theme to have more control over the post, like being able to shut off dates and name. 

 With Avenue you were able to click on a thumbnail then hit the BACK ARROW on computer or BACK BUTTON on smartphone and it would bring you back to where you were on the scroll (where ever the album cover thumbnail is). Now, with Brine, it brings you to the top of the page. This is a problem, especially with smartphones, given there are a 100 thumbnails per page arranged two per row. 

Is there a code fix that would make Brine behave like Avenue on this point. 

Below are captures from a desktop and smartphone

Hi ScottoCat - have you fixed this issue?  I previously posted the same question and did not get a response.
