DomSanitizer should keep style attributes in HTML, but sanitize them if needed

Current behavior

DOM sanitizer removes style attribute from all elements.

Expected behavior

DOM santitizer keeps the style attribute on elements, but sanitizes the actual style value if needed, so something innocuous like style="text-align: center" isn’t lost.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Displaying blog posts or other CMS content which uses inline styles for layout/styling.

Environment

Angular version: 4.3.6

Totally relevant because the only way to allow styles at the moment is to entirely trust the input. The use case for this is displaying user input from a rich text editor. I want to strip any dangerous bits about javascript, resourceURL and the such but keep the style attributes intact.

Thanks for reporting this issue. This issue is now obsolete due to changes in the recent releases. Please update to the most recent Angular version.

If the problem still exists in your application, please open a new issue and follow the instructions in the issue template.

@jessicajaniuk Updated the angular to the latest stable version which is now 13.2.5 and still have the issue - DomSanitizer still removes the style attr from html element in SecurityContext.HTML, so opening a new issue.
