The Bug
If the mouse scrolling sensitivity is lower than 1.00 in the control settings, then nothing will scroll in the trading interface with a resident
Reproduce
Get a villager
Trade with it until it is a Master
Set your scroll sensitivity to less then 1.00
Go back to the villager and scroll
Expected Result
You would be able to scroll
Observed Result
You couldn't scroll

But you're setting your sensitivity to 1.00, the whole bug is if your sensitivity is UNDER 1.00 is doesn't scroll.
I can confirm this on Linux in 1.19-pre5. It could be fixed by enabling RAW input and returning scroll sensitivity to 1.00.
