@freddy (it's been a while so I might be missing / misrepresenting some details) was never properly standardized, and lacked adoption and support. By contrast, , because it was supported by IE, did get used by a signifiant enough number of websites, notably in Asia. That forced Chrome, Firefox and Safari to support it to ensure compatibility with a bunch of legacy websites, and in turn eventually caused it to be specified in HTML5, though it's qualified as obsolete.
