346445 - Caret skips images when navigating using left/right arrows

Status: RESOLVED FIXED

(Core :: DOM: Selection, defect)

Description

[Uri Bernstein]

In caret browsing mode or Editor, placing the caret before a set of one or more images and pressing right-arrow skips the image(s) and places the caret after the first letter after the images.
Similarly, pressing left-arrow after images skips the images and moves the caret to before the last letter before the image(s).

The correct (and original) behavior is to treat images as if they were characters - each arrow-press should move the caret across one image only (and not the following character).

This is a (pretty old) regression, from bug 256252.

I'll attach a testcase immediately.
Assigning to myself since I have plans to work on the relevant code.
