Michael Kuhn 35edd8ea92 Fix clicking unread counter
When clicking the unread counter, the following exception occurs:
```
Uncaught TypeError: Cannot read properties of null (reading 'getAttribute')
```

This is due to `onClickMainMenuListItem` not working correctly for the
unread counter `span`s, which return `null` when using `querySelector`.
