51121 - Bad navigation in single line text edit with multiple lines

Status: RESOLVED WONTFIX

(Core :: DOM: Editor, defect, P5)

Description

[Ben Bucksch (:BenB)]

Reproduction:
1. Use a Unix build or set pref |editor.singleLine.pasteNewlines| to 0.
2. Copy multiple lines of text
3. Paste them in a single line text edit (e.g. the URLbar)
4. Try to get to the first line and back to the last

Actual result:
From bug 23485
- caret-up doesn't work, but home/caret-left does move to the previous line.
*Very* irritating.
- caret-down moves the caret one line down *on the screen* (i.e. it is under the
textedit field!) to the position where the second line would end, if it where a
2-line textarea.

Expected result:
caret-up down work just like in a multi-line text edit.

Additional comments:
See bug 50935 for why there can be multiple lines in a single line text edit.

ASSIGNing to buster per akk's comment in bug 50935 and because he knows the
discussion in bug 23485.

Comment 5

[rubydoo123]

just an fyi: 

on the mac a multiline paste into a single line text field (urlbar)results in a 
single line paste --> truncated at end of first line

on windows a multiline paste into a single line text field (urlbar)results in a 
single line paste --> truncated at end of first line

Removing myself as assignee for editor bugs, since the editor project is (sadly) long gone.

I think that we should drop supporting the value 0 from the pref because most web apps which has single line editors must not assume they may have multiple line value. Anyway, the navigation must be terrible because of no tests.
