(That was 7 years ago.)

The recipe to reproduce this bug is:

  !                      ;; input an exclamation mark (#x21)
  C-x 8 RET 2 0 E 4 RET  ;; COMBINING ENCLOSING UPWARD POINTING TRIANGLE
  RET                    ;; Newline
  C-x RET 8 2 6 A 0 RET  ;; WARNING SIGN

This gives me, on current master running on GNU/Linux:

!⃤
⚠

Besides the fact that the upper triangle is large and the warning sign
is small in my case, I see nothing untowards about this.

Is this all working correctly now, or is there anything left to be done?
Could this bug be closed?

Thanks in advance.
