Edited Issue: Razor ~/ resolution does not exactly work for all attributes [310]

Based on several blogs, one of them is http://vibrantcode.com/blog/2012/4/10/whats-new-in-razor-v2.html/, ~/ resolution should work for all attributes.

Well, that's not working for me.

I have the following content in my Index.cshtml view:
<h2 data-test="~/">Index</h2>
<a href="~/">Test</a>

The generated html:
<h2 data-test="~/">Index</h2>
<a href="/">Test</a>

It resolves for the href attribute, but not for the data-test attribute.
