Windows 10: Mini Micro Editor Horizontal Scroll Bar Bug (Shift + Mouse Wheel Not Working)

[Marutzo]

Description:
In the Mini Micro built-in editor (opened via edit), horizontal scrolling using Shift + Mouse Wheel does not work on Windows 10. The only way to scroll horizontally is by manually dragging the horizontal scroll bar, which slows down navigation in scripts with long lines.

Steps to Reproduce:

1. Launch Mini Micro on Windows 10.
2. Open the built-in editor by typing edit.
3. Enter or open a script that contains long lines that extend past the visible editor window width.
4. Attempt to scroll horizontally by holding Shift and using the mouse wheel.
5. Notice that no horizontal scrolling occurs.
6. Try dragging the horizontal scroll bar with the mouse — this works, but is less convenient.

Expected Behavior:
Holding Shift and scrolling with the mouse wheel should scroll the editor horizontally.

Actual Behavior:
No horizontal scrolling occurs when using Shift + Mouse Wheel in the Mini Micro editor.

Environment:

• OS: Windows 10
• Application: Mini Micro 1.2.5
• Input: Mouse with scroll wheel

Seems to work OK on MacOS. This might be a Unity issue. However it is a little fiddly sometimes; are you sure you clicked on the code editor (to ensure it has the focus) before attempting to scroll?

Indeed, I made sure to focus the editor, I tried clicking the scroll bar and drag it a bit and then scroll with the mouse wheel key combo, but this is something that has been like a completely missing feature for me for several years now in the Mini Micro editor, which is why I initially thought I should post this as a feature request rather than bug report. Not sure why it works on MacOS and not on Windows like I'm using, platform specific issue?
