 Hello everyone,

 I have noticed that the wordpress visual editor adds span tags with no
 reason. It happens when I create a bullet list or when I make a link.

 I am able to reproduce the bug for bullet lists but I cant do it for the
 links. It seems to happen randomly.

 To reproduce the bug for bullet list, I start with a title H3 then I click
 on the bullet list button. I start to write the list and then, when i save
 the draft, the first line has a span tag. This bug happens in several
 websites. Sometimes i get something like this :

 <li><span style="line-height: 12.997159004211426px;"><strong>
 or

 <span style="font-size: 13px; line-height: 19px;">

 I dont paste text from word to the visual editor. I write directy in the
 visual editor.

 For links, I dont know when it happens, but I sometimes have a <span
 style="color:#333333">.

 First, I thought i had the same bug than this one :
 http://core.trac.wordpress.org/ticket/23461 which said it was a "long
 standing bug in WebKit"
 but i had this bug in Firefox too which is not using Webkit but Gecko.

 Then i thought it was a bug with the add_editor_style() function but it's
 not that too. I commented the function but the bug still happens.
