Browse: Attachments: Current sorted column is not indicated for space attachments, which is inconsistent with page attachments

• Go to a Space containing attachments
• Select 'Browse' -> 'Attachments'
• Click on a column to sort by it

Expected: There should be an arrow to indicate the column which is being sorted on. This would make it consistent with the Page Attachments screen, which does show the sorted column. See screenshots.
