* Reenable HtmlBlock unit tests
* Add E2E tests for HTML Block cases
* Remove harded GenerateBaselines=true
* Fix#1193
This commit addresses the root cause of #1193. When we merge HTML
text nodes into HTML blocks we need to re-encode any HTML entities that
were encoded eariler.
I did a bit of a deep dive on how HTML encoding is handled in Blazor and
I think this is the best strategy. I think it's valuable that the
BrowserRenderer uses document.createTextNode, which will always encode
the text - this handles dynamic content. We want to keep this in place
to avoid HTML injection attacks.
* Fix#1265 Reenable MarkupBlock
* test cleanup
* Add HTML Block rewriter
* Baseline updates
* test gaps
* Update some unit tests to represent same behavior as before
* Define Markup frame type. Tests for rendering markup frames into render tree.
* Support markup frames during diffing (retain, insert, update, delete)
* Support markup blocks on WebAssembly
* Support rendering markup frames with server-side execution too
* Support markup blocks with multiple top-level nodes. Support updating markup dynamically.
* Define MarkupString type as a way to insert dynamic markup without needing custom RenderFragment code
* Remove comment
* CR: Better null value handling
