SiteConfig doesn't keep track of current Tab after editing a GridField record

[siteleas]

When you are in a Global Settings sub-tab and you click an elipsis on a data grid to edit it, then when you hit the < arrow at the top after editing, it takes you to the main sub-tab instead of back to the sub-tab that you were in before. This is a workflow problem and is confusing for the user as they don't know where they are and nor do they necessarily know where they should click to get back there.

This could be resolved by adding a hash value for the tab that they were on after the url i.e.- siteurl/admin/settings/#tab_name instead of siteurl/admin/settings/ for the '<' button.
