Spacing issues since 6.6 (Gutenberg with Block- or Hybrid Themes)

[dohu13]

Since version 6.6, all specific block spacings i’ve been setting in my theme.json file are ignored. For example, I defined my own margin for h2, which is now overwritten by the general BlockGap spacing. This code from the WordPress core seems to overwrite everything:

.is-layout-constrained > *,
.is-layout-flow > * {
margin-block-start: 3rem;
margin-block-end: 0;
}

In my theme.json I defined:
blockGap: 3rem (for general)
and h2 for example: margin: 2.5rem 0 2.5rem 0;

The margin, I defined for h2 are now overwritten by the margin-block-start (and end) commands.

Here is a screenshot of my testing site: ​http://test.lake-site.de/screenshot

As you can see, my own margin for h2 (defined in theme.json) is now overwritten by wordpress margin-block-start and margin-block-end taken from the BlockGap general settings (3rem) in theme.json. This happening now with all blocks.

@dohu13 Thanks for reporting the issue. It sounds like the same one mentioned here - ​https://github.com/WordPress/gutenberg/issues/53468#issuecomment-2241279024.

Is that correct?

If so, I'm currently working on a fix for it here - ​https://github.com/WordPress/gutenberg/pull/63972.

Yes that seems correct and looks like the same issue.

So I'm waiting for your fix. Thanks for your Feedback!
