iframe wrapper doesn't work properly

[akpp28]

I want my uploaded video to be of 100% width and the height should remain proportional.
In order to reach it, I use flag "config.youtube_responsive = true;".
After I've uploaded video, I want to add some text. In order to do that I click on the right side of the image and start typing.
As the result I get the following: div with class "youtube-embed-wrapper" copies each time when I click “enter”. Due to this, big indentations are left in the text:

<div class="youtube-embed-wrapper" style="...">
	<iframe ...>...</iframe>
</div>

<div class="youtube-embed-wrapper" style="...">my text</div> **(is created after press enter)**
<div class="youtube-embed-wrapper" style="...">my text2</div> **(is created after press enter)**
