Keep bundle, but disable minify not working

[marius-kazlauskas-trimble]

I am using Blazor (Server Side Rendering). I want to keep bundles, but disable minify. I have tried 3 different methods with no success:

1. Result: Bundle: Yes, but Minify is still ON

builder.Services.AddWebOptimizer(
    builder.Environment,
    new CssBundlingSettings { Minify = false },
    new CodeBundlingSettings { Minify = false },
    option =>
    {
        option.EnableCaching = true;
        option.EnableDiskCache = false;
        option.EnableMemoryCache = true;
        option.AllowEmptyBundle = true;
    },
    pipeline =>
    {
        pipeline.AddCssBundle("css/bundle.css", "css/a.css", "css/b.css");
        pipeline.AddJavaScriptBundle(
            "js/bundle.js",
            "javascript/a.js",
            "javascript/b.js"
        );
    }
);

2. Result: Bundle: No, Minify: No

builder.Services.AddWebOptimizer(minifyJavaScript: false, minifyCss: false);

builder.Services.AddWebOptimizer(
    pipeline =>
    {
        pipeline.AddCssBundle("css/bundle.css", "css/a.css", "css/b.css");
        pipeline.AddJavaScriptBundle(
            "js/bundle.js",
            "javascript/a.js",
            "javascript/b.js"
        );
    },
    option =>
    {
        option.EnableCaching = true;
        option.EnableDiskCache = false;
        option.EnableMemoryCache = true;
        option.AllowEmptyBundle = true;
    }
);

3. Result: Bundle: Yes, Minify: Yes

builder.Services.AddWebOptimizer(
    pipeline =>
    {
        pipeline.AddCssBundle("css/bundle.css", "css/a.css", "css/b.css");
        pipeline.AddJavaScriptBundle(
            "js/bundle.js",
            "javascript/a.js",
            "javascript/b.js"
        );
    },
    option =>
    {
        option.EnableCaching = true;
        option.EnableDiskCache = false;
        option.EnableMemoryCache = true;
        option.AllowEmptyBundle = true;
    }
);

builder.Services.AddWebOptimizer(minifyJavaScript: false, minifyCss: false);

Maybe there is some other way how keep bundle, but disable minify? I need this, because I need to keep bundles in my dev env.
