Description
IDLE doesn't have a horizontal scrollbar but that shouldn't stop the user from using their trackpad/touchpad to horizontally scroll the text. This is a small bug that can sometimes annoy people
Previously
If you try to scroll horizontally using a trackpad/touchpad, the text in IDLE would scroll vertically.

I tested the issue and the fix on: Windows 11, Ubuntu 24.04 and Debian 13. The issue appears on all OSes and the fix works on all of them. While I am not 100% sure if this will break on MacOS, I am very confident that there will be no problems.
