How can i limit the height of source window and simultaneously having scrolling capability?

[LinArcX]

For sources window, we have this option:
sources[number].max_item_count (type: number)

But i'm looking for an approach that limit the height of sources windows and let me scroll it simultaneously.

(We have this option in documentation window: documentation.maxheight (type: number))

I think pumheight is what you want.
