I use Chrome as well as Brave, which I highly recommend checking out. Here's how it looks in editor for me:
This site is so new, it's going to be an ongoing learning process for all of us. Each day I'm learning so much, and I still feel like a total newb sometimes.
In the end, we'll make this platform the best it can possibly be and this is why I am glad to have conversations like in this post to help ensure I am not hurting the site with my actions.
Oh wow.... you know what? I have that too, except mine by default comes up with the Markdown setup. I didn't even notice the Editor switchover link until I looked at your screenshot and compared it to my setup. Now I feel like a doof... lol!
Oh well, at least I learned something new today. XD
