This is part of #1723

When you hover over a contextual link of a block, you'll notice that the URL is something like /admin/structure/layouts/manage/default/configure-redirect/[block_hash]&destination=node#configure-block:[block_hash]. That helps us open the "Configure block" dialog for that specific block when we open the Layout admin UI. This is great, but it would be even more useful if in the locked background we scrolled to the specific region where the block is placed. Let me explain...

Say I want to configure the "Powered by Backdrop" block (which happens to be at the bottom of the page and the bottom of the Layout UI too). When I click on the "Configure block" contextual link, this is where I end up:

backdrop-configure_block_contextual_link-where_is_the_block

I think that it would be better UX if we actually scrolled down (using # anchors) to the part of the layout where the block is located. Like so:

backdrop-configure_block_contextual_link-there_it_is
