777449 - Kuma Editor: scrolling up is broken using the keyboard

Status: RESOLVED FIXED

Description

[Julien Wajsberg [:julienw]]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:14.0) Gecko/20100101 Firefox/14.0
Build ID: 20120624012213

Steps to reproduce:

- Open an editor with enough text in it (more than one screen), for example try to modify an existing article.
- click inside the editor
- go down using the keyboard arrow: it works correctly, scrolling down when necessary
- go up using the keyboard arrow: it doesn't scroll up as soon as the cursor is at the top; you have to press the arrow 4 or 5 times more so that it begins scrolling. And it doesn't scroll to the top at all, you have to use the mouse with the scrollbar (or your touchpad, etc)

Confirmed. Thank you for reporting this, Julien.

It looks like it does scroll part of the way up, but not all of the way up. See https://developer-dev.allizom.org/en-US/docs/Lorem_Ipsum$edit

yep, to me, it looks like the cursor goes up "outside" the page, and it's beginning scrolling up begins when the cursor is at the beginning of the page.

Can't explain it better, sorry :)

We are temporarily re-enabling the scrolling plugin, so this issue will re-appear. We will remove it again when bug 913441 is closed.
