Re-request review button navigates to unstyled /review-requests page

[domolitom]

Describe the bug

On a pull request page, clicking the re-request review button (circular arrows icon) next to a reviewer's name in the "Reviewers" sidebar navigates to github.com/<org>/<repo>/pull/<number>/review-requests. This page renders an unstyled, bare HTML list of reviewers instead of re-requesting the review.

Steps to reproduce

1. Open any pull request with assigned reviewers (e.g. [jaeger] Re-add anonymous Elasticsearch access support jaegertracing/helm-charts#743)
2. In the right sidebar under "Reviewers", click the re-request review button (circular arrows icon) next to a reviewer's name
3. Observe - browser navigates to /pull/743/review-requests showing an unstyled page

Expected behavior

Clicking the re-request review button should re-request a review from that reviewer without navigating away from the PR page.

Browser / OS
