Missing DependencySerializationTrait on FormLayoutBuilderConfigureSectionAlter

Thanks,

Strange that I had to re-add it for the block form alter, but yet not encountered the problem on section form alter.

I rechecked the commit https://git.drupalcode.org/project/ui_styles/-/commit/06c02af557a4b3ee15..., with LB block form alter it was the only 2 placed where DependencySerializationTrait was used.

Automatically closed - issue fixed for 2 weeks with no activity.
