Small bug on the Verge - link symbols sometimes visible

Not sure if I am the only one experiencing this but this happened across browsers and PCs. No extensions/add-ons installed.

I noticed them randomly. When I refreshed the page they were gone. I don't seem to get them on every article and maybe they even only appear after a certain time an article is open. I saw them in the Forum posts as well.

Did anybody else notice one of them?
