I was having my screen layout vary from Chrome to Firefox. The screen I’m loading is using a flex layout to slide frames around based on screen size.
On Firefox the scrollbars were appearing as I expected. Chrome was squashing all the frames to fit on a single screen and giving a scroll bar to each frame. I might be using the wrong webdev terminology. I’m not a web developer.
Anyway, I did an update on my Chrome browser and the problem went away.
I wanted to say something in case it is helpful to others.
General idea is to try a browser update if things aren’t laying out as you expect.
