Very slowly scrolling up in chat does not work

To reproduce:

1. Run /help to fill up the chat
2. Open chat
3. Very very slowly scroll up (move the mouse scroll wheel by one tick, wait a second, repeat)
4. Observe chat not scroll up

Scrolling up quicker and scrolling down at any speed work.

I am using a mouse with a physical scroll wheel, I tested two different mice of this kind. Attached is a forced crash report.

Note that the reproduction steps produce expected behavior in the creative mode inventory, proving that this is not caused by my hardware.
