I had the same experience. The page was jumping around and made it very difficult to read individual sections/bullets. I know it's tangential but it's not a great look for a FE tool.

Yep. Same for me. Was scrolling trying to read and it makes a big jump on its own for no reason. That’s a bad look in any case, and especially so when it’s the website for an FE tool.

Using Safari on iOS.

Didn't seem too bad. The header and some buttons on the main page are misaligned but the docs seem fine
