Please reintroduce the feature of arrow keys for vertical scrolling

Has anyone faced difficulties scrolling up and down using the keyboard’s arrow keys? In the newest version of ChatGPT web (updated last month), this functionality is no longer available.

I believe it would be beneficial for the developers to reinstate this feature.

I can scroll every website with arrow keys both vertically and horizontally except for ChatGPT web nowadays. I think it’s a bug or missing attributes in their code that should be fixed because browsers like Chrome support this functionality by default.
