Unable to search Pull Request ID

We're no longer able to search Pull Requests by ID, the search is only looking and plain text.

Expected Results:
When you enter the Pull requests search, you should be able to type in a pull request ID. The results should be the Pull Request that matches the ID.

Actual Results:
When you enter the Pull Requests search, and you enter a pull request ID. The results do not find the pull request as the search is only looking at plain text within the pull request description.

Workaround:
Disable "New pull request list experience"
