Hello,
I have come across a problem with the editor.
We have recently upgraded the telerik controls from V 2013 to V 2015.2.623.45.
After upgrade new version that some functionality are messed up.
Steps to reproduce the issue.
1 - Add below content HTML mode.
<html>
<head>
</head>
<body contenteditable="true">
T<span style="color: #00b050;">esting New Message twetw </span><span style="color: #00b050; background-color: #c4bd97;">werwrwerwrwrwrwrwrwrwrw<sup>rwerwrww<sub>rwrwrwrwrwr</sub></sup><sub>rwerwrewrwr</sub></span>
<p style="text-align: left;"><a name="Hello" href="http://www.bing.com" class="body">Hello</a><br />
<br />
</p>
<img src="https://www.google.co.in/images/srpr/logo11w.png" alt="bb" style="display: block; width: 78px; height: 116px; border: 9px solid #ff0000;" height="116px" width="78px" />
<p> </p>
<p> </p>
<p style="text-align: left;"> </p>
<p> </p>
<p><img alt="" src="https://www.google.co.in/images/srpr/logo11w.png" style="height: 74px; width: 371px;" height="100px" width="100px" /><br />
<br />
<br />
</p>
</body>
</html>
2 - Back to Design mode and set focus on Image
3 - Then go to HTML mode and back to Design mode.
4 - All content are selected on Design mode in Editor.
When move 3-4 time from Design to Html mode then getting script error "Uncaught TypeError: Cannot use 'in' operator to search for 'fontFamily' in undefined" as well.
This can easily be reproduced on your demo site as well(Chrome browser).
