Scrollbar tips (up and down single line)

PlatformIO v1.70.3 on Win7 (32 bit)

When working in the PIO IDE, there is a scrollbar to the right that works as expected.

Unexpected are missing endpoints, the tips or the up and down arrows (left and right on the horizontal scroll bar at the bottom) that allow for scrolling of only one (or a few) lines at a time.

Maybe this is a VSCode question? To tell the truth, I am new to this VSCode and PlatformIO and I am having a hard time figuring out where VSCode stops and PlatformIO starts.

Is the text editor part of VSCode?

Anyway, I went into settings, searched for scrollbar, and I can change the width or other but no mention of the end tips.

Thanks, Mark.
