Tested this out and works as expected. 👍
The change makes sense, make sure the global has the right value before render and replace it with the previous value after.

I think the change is solid, but there's a couple of things I don't know how to do:
It's a bit late over here so I'll leave the PR unmerged so others can chime in. |

In #26192 we refactored the block supports mechanism. It works by holding a global
$current_parsed_blocksreference that it uses to determine the attributes that it needs to add to blocks.However, when a block has inner blocks, that reference isn't updated so inner blocks end up inheriting the parent's properties (style and classes).
How to test
This is what I've done:
wp-includes/class-wp-block.phpclass with the contents of this PR.lielements) don't have thewp-social-linksclass attached. It should be present in the parent (ulelement).
