Workaround is just to open the unit search menu by left clicking an empty space in the graph instead of creating a unit from a connection.

Repro:
1. Have an open Bolt project and graph.
2. Create a connection from an existing graph node, drag to empty graph space to bring up unit options menu.
3. Search 'function exit'.

Expected result: Can create a function exit unit from the connection.
Actual result: Unit can't be found by search.

Marking as not a regression as I can repro in a6 and can't get an earlier version of Bolt 2 running.
