InnerBlocks doesn't show align wide/full controls when inside a custom block

[simom]

Description

I have a custom block that supports InnerBlocks, and if I remove the 'layout' support from the block.json, the InnerBlocks (which natively support wide/full alignment, like Group or Columns) no longer show the alignment toolbar control.

I have searched through tickets and tried to manually force the layout to be constrained to the innerBlockProps as suggested by @tellthemachines in this ticket #43731 (comment), but without success.

Am I doing something wrong?

Step-by-step reproduction instructions

• define a custom block with innerBlocks support
• make sure that there isn't the "layout" support in the block.json
• pass the layout constrained support to the innerBlockProps of the custom block
• add a group block inside the custom block

I think this is intentional. If the parent block (in this case, your custom block) does not support wide and full alignment, then logically, its inner blocks shouldn't support it either.

Try adding align: ['wide', 'full'] to your custom block.

Hi @SH4LIN, thanks for the reply. The parent block already has alignment support. I believe this should be possible since there shouldn't be a relation between the "layout" support and the alignment in theory (I know that there is a guard in the component). Following the example from the referenced ticket, it should be possible to enable the constrained mode even if the support is not present, or at least this is how I think it should work.
