Tabbing to Scrolling Text Boxes and 508

vicki Community Member Posts: 75 ♪ Opening Act ♪
Chrome, Edge, and IE do not allow a user to tab into a scrolling text box then use the arrow keys to scroll. Firefox does. Is there any workaround so that a title can be 508-compliant regardless of the browser used?

I am trying to get DHS approval on a course that must be 508-compliant and this is causing issues. I do not like Chrome!!!!!

Thanks for any input.
