Pulled and tested. Seems to work great!

Could we check whether passiveNode instanceof RenderedConnection instead of casting as any? At that point, I think we'd also be able to safely infer that it's one of passiveBlockConnection because they have same source block.

That's not the purpose for the cast, passiveBlockConnections is an array of RenderedConnection, so if it includes passiveNode, we know it is one; unfortunately without this, TS whinges that "Argument of type 'IFocusableNode' is not assignable to parameter of type 'RenderedConnection'.", stubbornly refusing to consider the possibility that the IFocusableNode passiveNode may in fact be a RenderedConnection (which implements IFocusableNode!). Since this is all verifiably safe I just casted to any to satisfy the compiler; doing an instanceof requires a full import of RenderedConnection, and IIRC that leads to an import cycle.

Ah, got it! I think that's totally reasonable then.

Proposed Changes
This PR reintroduces support for inserting blocks from the flyout at or near the currently focused node in the workspace. If a connection is focused, and the chosen block can connect to it, it will be initially moved to/proposed for connection at that point; otherwise, the focused node's parent block will be identified, and, assuming there is one, the inserted block will be proposed for connection to the first compatible connection on that block. A final attempt will be made to connect the inserted block to the focused block's parent block's input connection, after which the inserted block will just be initially proposed as a top-level block.
