Compilation error within tag attribute shows generated code instead of markup

[Eilon]

Create this Razor page (nothing else in the app really matters):

<a href="@doesNotExist">Hi!</a>

You get this error:

An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately.

Generated Code

The name 'doesNotExist123' does not exist in the current context

84.            Tuple.Create(Tuple.Create("", 11), Tuple.Create<System.Object, System.Int32>(doesNotExist123, 11), false));

Note that the error shows the generated code instead of the Razor markup.

This is using Razor 4.0.0-beta8-15751 (should be the newest beta8 release build).

BTW other errors show up fine. E.g. a random @foo in the page shows the markup and not the generated code.
