Delete -ms-text-size-adjust

[zh-Hans]

The -ms-text-size-adjust property will be ignored where the viewport tag is present.

Thanks, I didn't know that. But can't be sure that there will always be a viewport meta tag present in the HTML.

If this property is only for IE Mobile, I think it can be removed.
According to Jonathan Snook IE Mobile supports both the -webkit and -ms prefixes (correct me if I'm wrong):

IE Mobile for Windows Phone 7 has decided to implement support for -webkit-text-size-adjust. They'll also be adding their own duplicate vendor-specific prefix, -ms-text-size-adjust.

I don't know if those implementations are identical, if future versions of IE mobile will continue to use -webkit-text-size-adjust, or if both -webkit and -ms respond in the same way to the presence of the viewport meta tag.

One of the reasons why Microsoft broke vendor prefixes to support -webkit-text-size-adjust is because of how widespread it is, and because many developers are WebKit-focused at the expense of other mobile browsers.

Microsoft have implemented -ms-text-size-adjust. I don't want to actively contribute to developer over-focus on WebKit, and browser vendor temptation to support the prefixes of other vendors, by intentionally dropping the -ms prefixed version of the property.

For those reasons, and the ones given in the comment prior to this one, I'm closing this.
