Status labels in docs headings break section links

**Describe the bug**

Our new system for adding status labels in docs pages causes links to docs sections to break. It seems like the status label's text is included in the search for a matching page section, causing navigation to those sections to break.

Consider this heading:

```md
### Dense help text {{ status('updated') }}
```

This should allow you to navigate to that heading with `#dense-help-text`. However, you can only navigate to the requested heading by removing the status label.

**To Reproduce**

Steps to reproduce the behavior:

1. Checkout the repo
2. Find any docs heading that has a {{ status() }} label.
3. Attempt to navigate to it directly by appending the url encoding of the heading to your URL. I.E [colour-coding](https://vanillaframework.io/docs/patterns/badge#colour-coding) for a "Colour coding" section.
4. See that the requested heading is not scrolled to on page load. You should also see an error in console:
```
Uncaught TypeError: title is null
fixScroll http://0.0.0.0:8101/static/js/example.js?v=0134365:485

http://0.0.0.0:8101/static/js/example.js?v=0134365:512
example.js:485:7
```
5. Remove the status label from the markdown title. Retry navigating to the section.
6. See that the page scrolls to the requested section on load.

**Expected behavior**

Navigating to a documentation section by using a section name in a hash causes the browser to scroll to that section on load, regardless of status label.

Start with static/js/example.js, especially fixScroll around line 485, and reproduce the broken hash navigation using a documentation heading containing {{ status('updated') }}. Compare navigation with and without the status label; done means the browser scrolls to the requested section and the console error no longer occurs.
