ckeditor adds whitespace to tags in source

[routinet]

When adding text with simple formats, fckeditor is inject whitespace between the tags, and between the tags and the content. When retrieving the same text from the database, the injected whitespace is interpreted as additional content, which is wrapped in its own set of tags. Each of the new tags receives the same injection of whitespace. Example:

Simple text: <h1>text 1</h1> <h1>text 2</h1> <h1>text 3</h1>

After switch out and back into source: <h1>

text 1</h1>

<h1>

text 2</h1>

<h1>

text 3</h1>

After saving and reloading the text, and switching to source view:

<h1>

<br /> text 1</h1>

<p>

&nbsp;</p>

<h1>

<br /> text 2</h1>

<p>

&nbsp;</p>

<h1>

<br /> text 3</h1>

Doing the same again, with absolutely zero changes by the user:

<h1>

<br /> <br /> <br /> text 1</h1>

<p>

&nbsp;</p>

<p>

<br /> &nbsp;</p>

<p>

&nbsp;</p>

<h1>

<br /> <br /> <br /> text 2</h1>

<p>

&nbsp;</p>

<p>

<br /> &nbsp;</p>

<p>

&nbsp;</p>

<h1>

<br /> <br /> <br /> text 3</h1>
