Not sure if this really harms something, seems the tabs IDs are not used in any way. By the way, to be clean and have valid code I'd propose to review them. Currently, the HTML output is something like this:\r\n```\r\n<ul class=\"wpseo-metabox-tabs\" id=\"wpseo-metabox-tabs\" style=\"display: block;\">\r\n...\r\n<ul class=\"wpseo-metabox-tabs\" id=\"wpseo-metabox-tabs\" style=\"display: block;\">\r\n... etc.\r\n```\r\nMaking the IDs unique would be trivial, there's already the tab name we can append to the IDs but if they're not used in any way maybe they could be simply removed?\r\n/cc @omarreiss "}}
