Component is always being *replaced* (onWillStart is called)

I'm doing fairly big app and I notice that onWillUpdateProps is not being called when I expected. See this playground.

The XML code is quite simple

<templates>
  <div t-name="Greeter" class="greeter" t-on-click="tick">
    <Word word="state.word"/>
  </div>
  
  <div t-name="Word">
    <t t-esc="props.word"/>
  </div>

  <t t-name="Root">
    <Greeter />
  </t>
</templates>

And the function tick will simply cycle through several "Hello, World" phrases.

But in the logs I notice that Word is always calling onWillStart and never onWillUpdateProps. Is this expected? When is onWillUpdateProps really called?

hmm, from your example, i see this code:

    setup() {
        onWillStart(() => {
            console.debug("Word/onWillStart", this.props);
        });

        onWillUpdateProps((props) => {
            console.debug("Word/onWillStart", props);
        })
    }

if you look carefully, it looks like you are logging onWillStart in both case. I tried changing the log, and it look like it behave as I expect (logging onwillupdateprops)
