Patterns: Full width synced patterns inserted with constrained width

[jordesign]

Description

When inserting a synced pattern that was created at full width (outer block set with 'Full' alignment) it remains constrained to the content width.

When it is converted back to regular blocks - the 'full' alignment is restored

Step-by-step reproduction instructions

1. Create block (or series of blocks) where the outer most block has the alignment set to 'Full'.
2. Create a Synced pattern from the block/s
3. In a new page/post insert the synced block. It will insert as though it is constrained by the content area.
4. Convert the pattern to regular blocks. The pattern will return to the 'Full' alignment

This issue has actually always been an issue with reusable blocks (now called synced patterns). The original issue is #8288, so I am going to close this one to keep the conversation over there. Thanks for reporting this @jordesign 🙏
