13919 - can't un-list cleanly

Status: VERIFIED DUPLICATE of bug 28491

(Core :: DOM: Editor, defect, P3)

Description

[sujay]

using 9/15 build of apprunner

1) launch appruner
2) launch editor
3) click in a list in the Ender test page
4) keep toggling the list button on this list

notice it doesn't cleanly get out of list mode and back into it
like 4.x behavior...instead what I see:

a) it gets out of list mode
b) the cursor ends up on the left side of the next list item
c) you can't get back into the original state of the list.
d) you see screen glitch(layout) problems in and around the list.

basically you get into this messy state...I can easily reproduce this
one..

all platforms.

sounds like two bugs:

the first is that selection is not being reset properly.  I'll look into this.

the second is that when you make a list out of something, it's not being merged
in to any adjacent lists.  This is a design issue.  If I make them merge it will
fix this case, but what about the case where someone wants to make a list out of
something that is next to a list, but _wants_ it to be a seperate list?

accepting/ cc'ing steve and charlie for input.

i'll fix the selection part for m11 - the rest will have to wait (too doomed to
do list merging right now)

Difficult problem: I'd say that list merging when changing an adjacent non-list
paragraph is a good idea. If we don't, it wil become to easy to fracture a list
into un-mergeable sections, as we suffer from in 4.x versions.
If user doesn't want to merge, they should insert
another paragraph (or BR?) first. Thus the merging logic needs to pay attention
to intervening block tags (P, DIV, etc.) or BRs.

there are several issues witin this test
-- some bullet items actually disappear
-- an extra line feed was inserted between two list items -- that infamous
uneditable whiespace
-- highlighting a single list item, then selecting the list icon first indented
the list item and the following list item to the next inner level
-- when select the list icon twice it moved the list item and the following list
item to Normal.

moving to m14. Joe, if you can get to this sooner, then please change the
milestone.

[Joe Francis]

i believe some aspects of this bug may already be fixed.  But I'm moving it to 

m15 because I will not have time for list merging work during m14
