Hi,
Welcome to the forum and thanks so much for your report!
Inspecting the styles, I can see a font-size of 1.7em for the basic text and also for the link. Since the em unit always refers to the parent, the link is displayed much larger.
I’m not sure where and how you added the link style, but you should be able to solve the problem by either not assigning a font size to the link or by using 1em.
