Steps to reproduce:
1) Select the "talk" action, because the speech bubble makes a distinct cursor shape.
2) Go to the Select Character dialog.
The cursor should be an arrow/wedge shape while using this dialog (verified against DOSBox), but in ScummVM it's still a speech bubble.

Works now as far as I can tell.
