Horizontal scroll requires cursor on long lines since 1.101.0

[riya-amemiya]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.101.0
• OS Version: macOS 15.5

Steps to Reproduce:

1. Open a file with long lines that extend beyond the editor viewport width
2. Try to scroll horizontally using mouse/trackpad
3. Horizontal scrolling does not work at all

Expected behavior: In previous versions (before 1.101.0), I could scroll horizontally to view long lines that extend beyond the viewport.

Actual behavior: Horizontal scrolling doesn't work at all. The horizontal scrollbar may appear, but scrolling horizontally with mouse/trackpad has no effect.

Additional context: After updating to 1.101.0, horizontal scrolling stopped working completely. I'm not sure if this is a bug or if there's a new setting I need to configure. If there's a workaround or setting to restore horizontal scrolling functionality, I would appreciate the guidance.

I've recorded a GIF to demonstrate the issue, though it might be a bit difficult to see the problem clearly. I'll attach it below for reference.
