*@@* characters in razor view stop code generation without providing source file name #7421

Describe the bug

If Razor view contains *@@* characters (without space between *@ and @*), razor views are not added to output. Warning message does not contain view file name caused the issue.

To Reproduce

Create ASP.NET 6 MVC application. Add Razor view:

@if (true)
{
    using (Html.BeginForm("TooteParing", "Store", new
    {
    },
            FormMethod.Post, false,
            new
            {
                @class = ""
@*                @class = ""
*@@*                @class = ""
*@            }))
    {
    }
}

Re-build application and publish it.

Observed:

Output window contains message:

3>CSC : warning CS8785: Generator 'RazorSourceGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. Exception was of type 'ArgumentException' with message 'startCommentStar'

No view name caused error is provided in message and in output window even if Message level is set to Diagnostics in Visual Studio Build options.

Published application does not find views inside it.
