Confusing error message if iLoeb is not available (non-step indexed BI)

Example code:

From iris.proofmode Require Import tactics.

Lemma test `{PROP : bi} (k : nat) (Φ : nat → PROP) :
  Φ k -∗ Φ (S k).
Proof.
  iLöb as "IH".

(PROP should have type sbi)

Error message:

The term "coq_tactics.tac_löb ?Δ "IH" ?Q ?e ?y" has type
 "environments.envs_entails ?Δ ?Q" while it is expected to have type
 "--------------------------------------∗

 ".

I don't know if it is even possible, but it would be nice to detect this error and emit a nicer message.
