I noticed this using "add a link" on desktop in cswiki in production. The pulsing blue dot that encourages the user to click edit is there upon arrival to the page, but we don't want one at all.

This happens because HomepageHooks::onUserGetDefaultOptions defines a default value for the "did you see the blue dot for this task type" preference, but that doesn't apply to existing user accounts:

// Disable blue dot on Edit tab for link-recommendation tasks.
SuggestedEdits::GUIDANCE_BLUE_DOT_PREF => json_encode( [
    'vector' => [
        LinkRecommendationTaskTypeHandler::ID => true,
    ],
    'minerva' => [
        LinkRecommendationTaskTypeHandler::ID => true
    ]
] )
