Actually I has wrong the domiterator from the title, it's an implicit bug of IE selection system, because when we make the selection as described above, you can figure out from the elementpath that the selection is instead inside above paragraph.
We need a fix for the selection system.

Update ticket summary, it's not dedicate to br entermode anymore.

• We should not throw the error in the selection change check function. There could be unknown selection issues, and we must avoid them breaking the editor code at that point, considering that this function is executed hundreds of times during the editor life cycle.

• The checkSelectionChange looks like the wrong place for this fix. The problem is with the selection class itself, within the getRanges function probably.

• The changelog is missing.

I could not reproduce this issue on newest trunk using on any IE. After trying revision [3772] i was able to get JS error in IE 6 and 7 (although different then described in ticket description).

Maybe this fix is not necessary due to other changes ?

Unable to reproduce this bug anymore on trunk.
