8723	in chrome, span with class attribute removed when merging blocks on delete/backspace	alissa		"- set the enter mode to P or DIV
- set some style, for example bold to add span with class='bold'
- clean all text from the edited area
- press enter ({{{<p><br></p>}}} will be added)
- switch to bold
- write some text (you will have {{{<p><br></p><p><span class='bold'>aa</span></p>}}})
- go to the 1st line
- press delete

the expected result is that you'll get
{{{<p><span class='bold'>aa</span></p>}}}

but instead you get 
{{{<p>aa</p>}}}

I understand that this is a webkit bug, but unfortunately I guess that when they will fix the issue it will be with inline style instead of a class..
