The scroll wheel of my Mighty Mouse behaves incorrectly in the new textareas. Specifically: - the scrolling is too fast - text selection doesn't work properly after scrolling - text editing doesn't work properly after scrolling Please see the attached text case.

Apparently, three of the four problems have been fixed by the fix to rdar://problem/4644614: "REGRESSION: Typing, pasting or dragging in new text areas causes unnecessary scrolling". The scroll wheel's speed is still different, though: in the old textarea, I can't scroll it all with a single movement of the scroll wheel. In the new one I can. I don't know if this is the intended behavior.

Or maybe it was the fix to rdar://problem/4643238 "REGRESSION: Can't set insertion point at the end of a line of text" that fixed those bugs...

I see this bug with my Microsoft scroll mouse too. In the test case WebKit is more than three times faster scrolling the text area. Regression => P1.

Scrolling using the arrow buttons on the scrollbar also jumps too far. In Safari 2.0.4, four vertical button clicks will scroll just over 3 lines of text. In WebKit nightlies, one click scrolls about 3 lines of text! (I'm using a locally-built debug build of WebKit r18014.) Note that I've only tested vertical scrolling. Horizontal scrolling may be affected as well--I haven't tested it.

This scrolling behavior is intentional for all of our web page views and overflow areas. This behavior should probably be different for editable regions.

I'm not convinced we should fix this. Our scrolling internally is consistent, and I'm not sure we should special case textareas to be any different. If we do change it, I'd prefer one tick = one line to the old Safari behavior. Downgrading priority at least, since this is pretty minor.
