209909 - Caret movement inconsistent

Status: VERIFIED WORKSFORME

(Core :: DOM: Selection, defect)

Description

[Kai Engert (:KaiE:)]

Open the attached document in editor.
It shows two lines:
 x
 y

I can imagine 4 positions where the caret could be placed in this document:

1:
  |x
   y


2:
   x|
   y

3:
   x
  |y

4:
   x
   y|  

When starting at position 1 using arrow right repeatedly:

Expected behaviour:
  we arrive at positions 2, then 3, then 4

Actual behaviour:
  we arrive at 2, 4, but not at 3


When starting at position 4, we do arrive at positions 3, then 2, then 1 as
expected.

Mozilla 1.3 does not have this bug.

This is a regression starting with 1.4

I think this is a new regression.
when i using trunk20030608, I cannot reproduce this bug.
I also find info below when move caret:

It's not likely that I will work on editor/selection bugs in the near future.
Mass assining my bugs to nobody.
