Hey, sorry for the late response.
How did you zoom in? I tried this in my browser, but I don't know of any way to zoom here.
I just pressed crtl +. I tried restarting my computer, but that didn't help.
Got around to testing it myself, it seems ctrl and either '+' or '-' will zoom in or out, but it goes from default to impossibly small or large.
Maybe you can delete your cookies if + and - can't help to get back to default
