**Describe the bug**

I'm using:

https://github.com/GoogleChrome/chrome-extensions-samples/blob/main/functional-samples/cookbook.sidepanel-open/script.js

But the sidepanel stays open for all the tabs.

**To Reproduce**
Steps to reproduce the behavior, or file the issue is found in:

1. Go to ['cookbook'](https://github.com/GoogleChrome/chrome-extensions-samples/blob/main/functional-samples/cookbook.sidepanel-open/script.js)
2. Copy and paste the code to your code (background script)
3. Install and open sidePanel -> sidePanel on all tabs.

**Expected behavior**

SidePanel only open for the active tab

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Notes**
Anything additional here. 🌈

Start with functional-samples/cookbook.sidepanel-open/script.js and reproduce the reported behavior using the listed steps. Trace how the sample opens the side panel and compare the observed tab scope with the expected active-tab-only behavior. Done means the sample reliably keeps the side panel limited to the intended tab.
