@no-reply @vantuyls Looks like the element <div id="sortAndPerPage" class="clearfix"> which houses these buttons is coming from Blacklight. I put the "Blacklight" label on it, and will kick this to the bottom of the current Hyrax WG Sprint Ready column.

I believe this is happening because activating these buttons is causing a new page to be loaded. So the focus starts over at the top of the page. I believe I see the same problem manifest on https://demo.projectblacklight.org

@jcoyne Yes, you're right the selection is causing a new page load which will make retaining focus on the element tricky. Maybe we evaluate the cost of a solution vs. the cost of keeping this as-is.

@h-parekh I wonder if the solution for you is to not use Turbolinks?

Issue is still present in Hyrax 3.0.0.pre.rc3.

Need to check if this issue is a known issue in Blacklight or if it is fixed in a later version. If there is an open issue, link that issue here. If no issue or fix, create an issue for Blacklight (and we might do the work to fix and contribute back but at least it will be reported).
