Incompatibility with Layout Builder iFrame Modal module

Ooo ya, I guess we broke that integration huh? You can see that in lb_plus_contextual_links_alter we are overriding the layout builder contextual links to add nested section storage support. That gives users the ability to place a block who's layout is managed with layout builder inside a layout. It makes for a block builder like functionality. Right now we have it to where block editing happens in the sidebar, but we are going to make that sidebar expandable and able to pop out into a modal and hopefully popout into another window too if that's possible.
