In Chrome SPAN tags appear when merging paragraphs with delete/backspace.

[lmeurs]

Occurs in Chrome v24.0.1312.56 / CKEditor 4.0.1 (revision d02739b) / CKEditor 4 DEV (Standard) (revision d02739b) (nightly build demo)

Did not occur in Firefox v17.0.1

When you have a paragraph with several lines of text, ie.:

<p>line1<br />
line2</p>

and want to create 2 separate paragraphs, you could go with your cursor to the end of line1, press ENTER to create a new paragraph and press DELETE to remove the whiteline caused by the BR tag. Then CKEditor puts some HTML in a SPAN tag with a line-height styling.

<p>line1</p>
<p><span style="line-height: 1.6em;">line2</span></p>

Other examples: It also happens when trying to create a single line out of the next cases:

<p><br />
line2</p>

and

<p>line1</p>
<p>line2</p>

EDIT:

• This happens when two paragraphs are joined with delete. Tag br has nothing to do here.

Content: <h1>^test</h1> + enter + backspace creates awful mess.

Problem can be reproduced from CKEditor 4.0 in Chrome only.

I started to feel that we can't rely on Webkit's backspace behaviour any more. Those styling spans are unacceptable thus I'm changing priority to high.
