bug: Calling ion-reorder-group's complete with false doesn't reset ion-reorder's position

[ghost]

Bug Report

Ionic version:

[x] 4.x

Current behavior:
Passing false to ion-reorder-group's complete doesn't reset the position of the dragged ion-reorder component.

Expected behavior:
Passing false to ion-reorder-group's complete should reset the position of the dragged ion-reorder component to its pre-dragged state.

Steps to reproduce:
StackBlitz: https://stackblitz.com/edit/ionic-v4-angular-tabs-nudxur

event.detail.complete(false); // should reset the reorder component's position

Other Information:
Looks like this broke in bd96491 (see this line).

Could presumably be fixed by changing

if (toIndex !== fromIndex && (!listOrReorder || listOrReorder === true)) {

to

if (toIndex !== fromIndex && (listOrReorder === undefined || listOrReorder === true)) {

or similar.

This worked for me:
event.detail.complete({ listOrReorder: false });

Looks like the documentation needs to be updated.

Looks like the documentation needs to be updated.

I believe it's still a bug and your first fix suggestion is correct.
@Yogatopia provided nice workaround, but we can use any nonempty object to get the same effect.
event.detail.complete({ any: "thing" });
works for me as well, which doesn't seem a proper API.

Yeah, that definitely doesn't look like intended behavior.
