Exception is being thrown on context menu in bulletlist

[Marek Lewandowski]

since: 4.3 until major

Touches opera/chrome (dont know about the others). So far i have reproduced it on Windows only, Olek says that he can't repro it with Opera+OSX

1. open /samples/inlineall.html

( there is a bullet list starting with string "Ut sagittis, nunc liber" )

2. click in order to position caret in following place (but does not have to be exatly the same):

Ut sagittis^{, nunc liber}

3. Right click mouse in the same place (to show context menu)

(if you are on chorme: )

4. now that context menu is open click LMB once again
5. ... and click RMB once more : )

Current result:

Uncaught TypeError: Cannot call method 'getAttribute' of null
