482943 - don't scroll pane when dropping message on top or bottom folder in folder pane

Status: RESOLVED WORKSFORME

(Thunderbird :: Folder and Message Lists, defect)

Description

[Wayne Mery (:wsmwk)]

don't scroll pane when dropping message on top or bottom folder in folder pane

1. pick a folder that is not first folder of the folder pane
2. position the folder to be the top folder in the pane view
3. drag a message to it from some other folder

expected results: folder doesn't move on me
actual results: folder scrolls 
this behavior is most annoying

Is this within Thunderbird's control?
Or, is this ultimately an xul core issue?

Is this a tree and the drag-scrolls-tree behaviour isn't precise enough? I think it is done this way because the tree doesn't receive dragover events unless actually dragging over the tree.

Perhaps. But seems like there should be some allowance for being able to drop on that first or last row in view

I'm happy to say this is much improved in version 115. (not sure whether it's perfect)
