Inserting media in SunEditor 3 beta20 creates an extra element

[EricBCoding]

Describe the bug
When inserting an image (or other media, such as a drawing) into the editor, it will produce an extra element after the media. This element appears to take on the properties (i.e. block type, styles, classes) of the element that should follow the media. It contains a <br>.

To Reproduce
Steps to reproduce the behavior:

1. Go to official demo: http://suneditor.com/v3/cdn_test.html
2. Enter some basic text, change it from paragraph to a heading to make the problem more obvious
3. Insert media
4. Check source code

Expected behavior
Inserting media should only produce HTML required for the media

The "componentAutoSelect" option is set to "false" by default.
When this option is true, the inserted media will be selected after inserting the media,
but when it is false, a line that is the same as the line that had focus will be added below the media.

In the current demo I changed that option to "true", so please test it.

It might seem strange. I'll think about how to do this part naturally.

Thank you, @JiHong88 ! I can confirm that enabling "componentAutoSelect" allows me to insert media without the extra markup.

Actually, it's working in my local environment, but not in the official demo:

Is there a benefit or usecase for having this option disabled? 🤔 It seems to me that duplicating an element would be undesirable in most situations and shouldn't be the default behavior, but maybe I'm overlooking something.
