Description
I wish we could see how the tactic state changes before and after semicolons.
I asked Mario about this in this Zulip thread: https://leanprover.zulipchat.com/#narrow/stream/113488-general/topic/semicolon.20and.20tactic.20state
Apparently this requires changes to the global parser?

Research direction
Start by reading the global parser and tactic-state display code; the issue does not name specific files or tests. Review the linked Zulip discussion for context on the semicolon behavior and parser constraints. Done means the tactic state can be observed both before and after semicolons.
