The Review Request page's main view, RB.ReviewRequestPage.PageView,
lived in a pageView.js file. This is being blacklisted by recent
uBlock Origin releases, and likely other ad blockers. To fix this, the
file (and the class) have been renamed. The new naming is a bit
redundant with the directory name, but won't trip up any ad blockers.
