Steps to Reproduce:

1. open a pr Align chat title container with centered interactive-session content vscode#291564 in vscode with the pr extension
2. notice that there are inconsistenies between the two (as shown below in the screenshots):
   the page in PR extension missed the events of title changes, new commits, ready to review, emoji support, label changes.

This is expected, we don't try to replicate everything that GitHub.com does.
