Media & Text block: wide alignment is not being passed to render_block filter

[webmandesign]

Describe the bug
Looking at the block attributes passed to render_block filter, the align attribute is not set even if the wide alignment is chosen in the editor for Media & Text block.

Maybe caused by wide alignment being a default value for Media & Text block?

To reproduce
Steps to reproduce the behavior:

1. Insert a Media & Text block into post content, set an image and text. Do not tweak any other options - the block should have wide alignment applied by default.
2. Publish the post.
3. Check the output of the $block parameter of render_block filter (in front-end). You can see there is no align attribute under $block['attrs'].

Expected behavior
Alignment value should be passed to render_block filter even if the block uses a specific alignment value by default. (Actually, all default values of block attributes should be passed into render_block filter.)

Additional context

• Tested on WP 5.2.2

Hi @webmandesign, thank you for reporting this issue. The issue is happening because wide align is the default align attribute for media & text bloc. The problem is common to all default attributes in every block.
Previously default attributes were not passed to render_block because the server may have not been aware of them. With the block.json work maybe we can now pass default values when they are known on the server. Any thoughts on this @gziolo?

Thanks for the info @jorgefilipecosta
I thought it could be the case. Would be really great if default atts could be passed to the render_block filter. They are significant part of the block appearance.

The long term idea is to register all core blocks on the server using block.json. It will solve the issue for all the regular attributes but not necessarily for align which is kind of special when used through supports: align construct. We will still have to develop the compatibility layer which will inject this attribute on the server for all those blocks which will enable support: align.

Hi @webmandesign I am not able to reproduce this with WP 6.2.2 and Gutenberg trunk, is this still an issue?
The block is not wide by default anymore, but when an alignment is used, I see the attribute when I dump the result of the render_block.

Hi @carolinan I guess this is resolved now after those years ;) You can close the issue.
