Prerequisites

Please put an X between the brackets as you perform the following steps:

• Check that your issue is not already filed:
  https://github.com/leanprover/lean4/issues
• Reduce the issue to a minimal, self-contained, reproducible test case.
  Avoid dependencies to Mathlib or Batteries.
• Test your test case against the latest nightly release, for example on
  https://live.lean-lang.org/#project=lean-nightly
  (You can also use the settings there to switch to “Lean nightly”)

Description

In the example below, Prod.continuous is a partially-typed declaration name.

structure ContinuousSMul (M X : Type) : Prop where
structure ContinuousAdd (X : Type) : Prop where

theorem Prod.continuousSMul {M X Y : Type} : ContinuousSMul M (X × Y) := ⟨⟩

theorem Prod.continuousAdd {X Y : Type} : ContinuousAdd (X × Y) := ⟨⟩

example : (ContinuousSMul Nat (Nat × Nat)) ∧ (ContinuousAdd (Nat × Nat)) := by
  exact ⟨Prod.continuousSMul, Prod.continuous⟩ -- put cursor after `s` in `Prod.continuous`
                                               -- and ctrl-space fails for me

I would expect autocompletion in VS Code to offer me e.g. Prod.continuousAdd (the thing which will close the goal), but for me it offers nothing:

Steps to Reproduce

1. Copy the code above into Lean
2. Put cursor after s in Prod.continuous
3. ctrl-space

An even simpler failure:

example : True ∧ True := by
  exact ⟨trivial, True.in⟩

This is showing the wrong intro
