Links in PR comments getting 'clicked' without user action

Hi all,

Having a slightly weird issue. We have an automation thing which leaves comments on PRs with a link to trigger off translations in our i18n SaaS provider. It seems that, shortly after the comment is created, a GET request is made to the HREF in the background somewhere. The user agent is:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36

Is there some link-scanning thing that’s been added to Github recently? (This didn’t use to happen until about a month or two ago as far as I can tell).
