Hello,

I don't see any issue according to your screen record. It's just the code suggestion to complete or close the HTML tag. You can simply type it manually.
The new version of the View editor might be a little bit different from the old one. Here is the screen record on my end https://drive.google.com/file/d/1kIWmdme1mJGpydJ9bPViOu9lTmXBRFRl/view?usp=drive_link
