BUG: ViewComponentContext.ViewContext.ViewData.Values is null aft

BUG: ViewComponentContext.ViewContext.ViewData.Values is null after upgrade to 12.20.3

On some blocks I have this code snippet in order to get which size the block has.

var renderSettings = ViewComponentContext.ViewContext.ViewData.Values.FirstOrDefault() as Dictionary<string, object>;
var tag = renderSettings["tag"] as string;

After upgrade to 12.20.3 ViewComponentContext.ViewContext.ViewData.Values are null all of a sudden, which seems like a bug.

On another site we try to fetch customcss (that's added as an additionalViewData in ContentArea PropertyFor) which also is null all of a sudden after upgrade.

ViewComponentContext.ViewData["customcss"]

I can't pinpoint exactly which package that broke this, but these are the packages I've updated:

It worked as expected in 12.20.1

Shouldn't you be able to access that using the ViewBag?

E.g

ViewBag.customcss

Just checked and ViewBag.customcss (or whatever I'm looking for) is empty.

Just upgraded to the latest version and we still have the issue with both ViewBag and ViewData:

I've also tried remaking my block until a bare minimum Async version, but still both the ViewData and ViewBag are empty.

Here are my installed packages:

Am I missing something here?

This is the response I've got

There are some special tags that will not be passed along when you have nested content areas, Other custom keys should be passed along

That is due to the related issue [CMS-27573]

If the partner would like to pass along view data in a nested content area, I guess they could do it like this in the nested view:

@Html.PropertyFor(m => m.ContentArea, { Tag = ViewData["tag"} )

What we're trying to pass along are these standard "Display As".

I tried implementing the PropertyFor you suggested in ContainerBlock (the parent of ContainerColumnBlock) as well as on the ContainerColumnBlock but the ViewData and ViewBag is still empty.

You probably want to make sure you updated EPiServer.Cms.AspNetCore.HtmlHelpers to 12.21.1, not just the cms.core

After installing EPiServer.Cms.AspNetCore.HtmlHelpers it seems to have resolved the issue for us, thanks :)
