Incorrect background color setting while changing font size.

[Krzysztof Studnik]

1. Set text background color to background-color:#0000ff or any other.
2. Type few characters and press space
3. Change font size to bigger one
4. Repeat step 2 and 3 until font size 72

Expected

Each part of text should have its own background, height of background is set according to font size.
Example:

<p>
	<span style="font-size:24px;"><span style="background-color:#0000ff;">asd </span><span style="font-size:36px;"><span style="background-color:#0000ff;">asd </span><span style="font-size:72px;"><span style="background-color:#0000ff;">asd </span></span></span></span></p>

Actual

<p>
	<span style="background-color:#0000cd;">asd<span style="font-size: 16px;"> asd<span style="font-size: 20px;"> asd<span style="font-size: 24px;"> asd <span style="font-size: 72px;">asd</span></span></span></span></span></p>

additional info

I was able to reproduce this under FF since cke30, under webkit browsers since 3.5.3 (afer "setting style on colapsed selection" was solved)

Reproducible in all browsers from CKE 3.0.

From the ticket #8437 you can see that same thing can be reproduced when pasting from Word.

IMO if CKEditor could wisely switch spans from

<span style="background:lime;">
       <span style="color:white;">
           <span style="font-size:36.0pt;">WORD</span>
       </span>
</span>

to (size around background color)

<span style="font-size:36.0pt;">
    <span style="background:teal;">
         <span style="color:white;">ABC</span>
</span>

Problem would be solved .

Just a note - #3599 says that this issue is supposed to be fixed.

DUP of #5503
