Reviewed by Charlie Wolfe.
ResourceLoadStatisticsStore::aggregatedThirdPartyData uses the third-party
cookie blocking mode to decide whether to filter results by prevalence.
With ThirdPartyCookieBlockingMode::All it returns all third-party domains;
otherwise it returns only prevalent ones.
When OPT_IN_PARTITIONED_COOKIES is enabled, propagateSettingUpdates()
, fires during [webView loadHTMLString:...] in the test,automatically
upgrades All to AllExceptPartitioned when any page has
OptInPartitionedCookiesEnabled (which defaults to true). This caused
aggregatedThirdPartyData to incorrectly filter out non-prevalent domains
even though the intent was to block all third-party cookies.
This fix extends the "show all" condition to include AllExceptPartitioned,
which blocks all third-party cookies in the same way as All.
