The selected properties are lost when I edit inserted powerpoint

Content

Hi All

In WYSIWYG Course Editor, when I insert a powerpoint file,  I choose a value for layout  and a value for style. In current, I can't retrieve the layout information of PowerPoint on the second time I edit the object, the same problem happens on Video, Audio and so on, it is existing limitation. I can't retrieve the style  information of PowerPoint on the second time you edit the object,too.

Have you ever seen this case yet?
