cannot bypass buttons using left/right arrows

[kae]

if your cursor is to the left of a button, you cannot skip past the button by hitting the right arrow (and vice versa).

to test:

1. open demo FCKeditor 2.4.3
   
2. select all existing content and hit delete.
   
3. insert new Button
   
4. try navigating to the left or right.

the bug is similar to #739, but not quite the same
tested in Firefox

Confirmed in FF2. Works fine in IE and IE7

[Artur Formella]

The same bug occurs in CKEditor 3.0 beta 3667. Works fine if there is some content before and after the button.

This is no longer an issue in latest Firefox 19.0.2 and CKEditor 4.0.2 thus I'm closing it as fixed.

There are still other issues however like no ability to edit form elements - #5804
