Please describe the bug

For citations, if the link in Markdown (activity.text) and entities[@id=""].citation[].appearance.link differs, then depends on where the user click the link, it will open different site.

Markdown footnote-style link reference should be the source of truth.

Do you see any errors in console log?

How to reproduce the issue?

1. Go to https://compulim.github.io/webchat-loader
2. Paste the chat history
3. Open the link via footnote-style link reference and citation

What do you expect?

Both link should go to https://bing.com/.

What actually happened?

When the citation link is clicked, it goes to https://google.com/.

No file or test is named in the issue. Start by tracing how chat history renders Markdown footnote-style links and citation appearance links, then reproduce the supplied chat history; done means both links use the Markdown reference URL, including when citation URLs differ or are absent.
