Zero star rating on plugins details page (in WP, not web)

[zodiac1978]

After clicking on the details link from the Yoast plugin in the plugin list table I get a strange behavior. Below the know 1 to 5 star rating there is an additional line with "0 stars", linking to ​https://wordpress.org/support/plugin/wordpress-seo/reviews/?filter=0

The link just shows all reviews.

On the web page it does not show this behavior:

Details page showing non typical 0 star line (here in German website, therefore "0 Sterne")

@clorith already had some ideas how this happens:

That's very likely that weirdness where stars disappeared when something got flagged, so it has 0 as Metadata, I think it was fixed, but might have been a cache in validation kicked up some dust there

Might be worth a meta ticket, since that's on the api side, and not the direct functions dotorg uses to look up ratings (dotorg got better at handling separations and missing data, and I have a suspicion the same enhancements never made it to the api)

In this case, the issue is that a review from 2012 quite literally had 0 stars recorded against it.

I've fixed up that review and the UI should show correctly within a few hours.

To protect against this for other plugins (The ratings table has some bad data for 2012-2015 it seems, I can't correct it all retroactively) I've made a change to the library we use to exclude ratings that fall outside of the 1..5 range:

r17382-dotorg
Ratings: Exclude any ratings counts that are not expected.
