The Strip Css Formatting option in Rich Text Editor does not remove all inline styles. Using the following markup:
<h3 style="color: #222222; background-color: #ffffff; margin: 1em 0px; padding: 0px; line-height: 1.3em;">Q: What is the outlook for the U.S. economy, as well as fiscal and monetary policy?</h3>
<p style="color:#ff0000; background-color: #000;"> HELLO </p>
<p style="color:#ffff00; background-color:#000;"> <span style="font-weight: bold; color: #ffffff;">jello </span></p>
Results in:
<h3>Q: What is the outlook for the U.S. economy, as well as fiscal and monetary policy?</h3>
<p> HELLO </p>
<p> <span style="color: #ffffff;">jello </span></p>
As you can see the last inline style was not stripped out. Is there any explanation for that behavior?
