Provide the steps to reproduce

1. Run LH on https://fatllama.com

What is the current behavior?

It shows this suggestion.

What is the expected behavior?

It doesn't show this suggestion, as I already preconnect to 5 domains in the homepage:

    <!-- preconnect 5 most costly connections https://www.webpagetest.org/forums/showthread.php?tid=15317 -->
    <link rel='preconnect' href='//api.segment.io' />
    <link rel='preconnect' href='//stats.pusher.com' />
    <link rel='preconnect' href='//m.stripe.com' />
    <link rel='preconnect' href='//www.google-analytics.com' />
    <link rel='preconnect' href='//js.intercomcdn.com' />
    <!-- preconnect end -->

According to #3106 , no more than 5 preconnections should be done for best performance. LH asks me to do a lot more:
