It does look bigger without the space, you need to not be using an app with a horrible poverty renderer
Is the sopuli website an app with a poverty renderer? Because it’s broken there.
Kinda seems like whatever you’re using has non-standard rendering.
The website isn’t the issue, the issue is that your browser isn’t implementing Lemmy’s version of markdown correctly.
I’m not on sopuli. You are. I checked to see if it’s on my end, but it’s on your site, too. In all browsers.
Edit: And lemmy’s documentation on markdown includes a space. It seems whatever app you’re using didn’t implement markdown correctly. No one outside the app will see it correctly unless their app also messed it up.
