WYSIWYG Editor is adding extra code to images after update, so image is not showing

[ivagarfittmage]

So if I want to edit code that is there and click Show/Hide Editor button and change text, then click Sace and continue edit all the images are removed and not showing on the front.

What exactly extra code is added?

I'm having this same issue in Magento 2.

Here's my code

<div class="social">
	<a class="twitter" href="https://twitter.com/twitter" target="_blank"></a>
	<a class="googleplus" href="https://plus.google.com/+google" target="_blank"></a>
	<a class="instagram" href="https://www.instagram.com/instagram/" target="_blank"></a>
        <a class="facebook" href="https://www.facebook.com/facebook" target="_blank"></a>
</div>

When I click the "Show / Hide Editor" button it shows the WYSIWYG but there's no code. It's just empty. Then when I hit the button again the WYSIWYG goes away but the block is blank. The code doesn't come back. Other times when I click the"Show / Hide Editor" button the other buttons "Insert Widget" "Insert Variable" "Insert Image" will all disappear and the WYSIWYG never shows up.
