Play when visible is not working

[RostVY]

Quote from readme:

Play if canvas is visible

<canvas #canvas="rivCanvas" riv="knight" width="500" height="500">
  <riv-animation name="idle" [name]="canvas.isVisible | async"></riv-animation>
</canvas>

First: I believe, it should be something like

<riv-animation name="idle" [play]="canvas.whenVisible | async"></riv-animation>

Second the playback control over [play] input is not working at all.
I have a component which has play = false; and template:

<canvas [riv]="animation" width="640" height="325">
    <riv-animation [name]="animationName" [play]="play"></riv-animation>
</canvas>

<button (click)="play = !play">Play</button> {{play}}

Clicking button changes the play property, but animation does not start.

Using Angular 16.2.12, ng-rive 0.3.1
