When setting a SPAN element to contentEditable=true, the user can add text but can not delete using backspace or delete keys. The only way is to select it using the mouse or using shift + arrow keys. When changing the span element to div and setting display:inline the problem is fixed.

Reproducible: Always

Steps to Reproduce:
1.add <div>text:<span contentEditable=true>cant delete this</span></div>
2.try to erase text inside the span
Actual Results:  
The text can not be deleted using backspace or delete keys

Expected Results:  
The text shuld be deletable using the keys

Using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729) in XP home I can delete chars EXCEPT the last character in an inline contenteditable using DEL-key (backspace works) when I have entered the element by clicking. If I enter the element using arrow-keys, even the last char can be deleted.

if I add
<span contenteditable="true" onclick="this.blur()">
then I can delete even the rightmost character, even when clicking in.

I'm able to delete all chars except the last one in the provided example.
I have more examples. I'm not able to delete any char in the following:
1)
<p><span><span contenteditable="true">try to delete me</span></span></p>
2)
<pre><code><span contenteditable="true">try to delete me</span></code></pre>


I'm able to reproduce it on Windows and Linux:
