Subject: 31.0.50; Feature-Request: Always keep cursor's position when pixel
 scrolling
Date: Sat, 04 Jan 2025 08:50:04 +0800

Recently, when the cursor is inside the screen, it's positon will not
move when pixel scrolling. But when the cursor touching the bording of
window, it's position begin to change.

expected:

1. when the cursor(line) is closed to the border of window, partially-visible
the cursor
2. when the cursor(line) is outside the window, hide the cursor
3. wehn the cursor(line) is inside the window, show the cursor again

Or there already an option to enable this feature?

As I known, Apple Xcode and Microsoft Word have the same behavior as
describe above.
