The now-deprecated GLIB API involved adding new types of website data to WebkitWebsiteDataManager in the WPE/GTK API, but if this step wasn't performed, that would result in website data being leaked outside specified directories, which was a serious privacy issue. We corrected this in 253824@main in later 2022. That is why, as we moved forward building the new GLIB API, we used base data and cache directories for tests website data configuration in 259132@main. As time went on the bots for this particular data configuration test (TestWebSiteData/configuration) began to fail consistently.
