Cover image as featured image + "Fixed background" duplicates the style element.

[Gierand]

Description

Adding a cover image as featured image with the "Fixed background" option duplicates the style element, which will result in the following code on the frontend:

<div class="wp-block-cover is-light has-parallax" style="background-image:url(PATH_TO_IMAGE);" style="margin-top:111px">

Step-by-step reproduction instructions

1. Create a new post.
2. Add featured image.
3. Add cover block as featured image.
4. In Media settings check "Fixed background".
5. Add any custom styles (margin or padding).

This is where the solution in #42128 shines and the discussion in #42485 is a turning point for this: having one way to handle block rendering (with a tokenizer or not) would prevent these mistakes.

Also: tested and confirmed the bug. Wish I'd have tested this earlier :)

@sunil25393 I can't repro this either. @Gierand I'll close this but feel free to reopen if the problem persist for you.
