[Bug]: Since v7.2.0: Actions tab doesn't show count anymore + console error

[Spielboerg]

Describe the bug

After updating to v7.2 the number of actions is not shown in the tab anymore (top: v7.1, bottom: v7.2):

Also, the console is flooded with errors (1 per event/action):

The error is happening in this Storybook component:

function Title() {
  let[{count},setCount] = useAddonState(ADDON_ID, {
    count: 0
  });
  return useChannel({
    [EVENT_ID]: ()=>{
      setCount(c=>({
        ...c,
        count: c.count + 1          // ← c is undefined
      }));
    }
    ,
    [STORY_CHANGED]: ()=>{
      setCount(c=>({
        ...c,
        count: 0
      }));
    }
    ,
    [CLEAR_ID]: ()=>{
      setCount(c=>({
        ...c,
        count: 0
      }));
    }
  }),
  React.createElement("div", null, React.createElement(Spaced, {
    col: 1
  }, React.createElement("span", {
    style: {
      display: "inline-block",
      verticalAlign: "middle"
    }
  }, "Actions"), count === 0 ? "" : React.createElement(Badge, {
    status: "neutral"
  }, count)))
}

To Reproduce

Unfortunately, I can't reproduce the problem in the provided stackblitz. But since it works in v7.1 without having changed anything and it is related to a component of Storybook, I hope you can fix it.

I'm seeing this as well, also started with upgrade to Storybook 7.2. I independently came to the same conclusion as @Spielboerg .

I see this as well in 7.3.1. If I click away to a different story and back to my other story, then the counter works again...

I'm on 7.4.0 now and still seeing what @liu351 is seeing.

It works fine again for me on 7.4.0
