Issue when creating a quote with HTML content

Reported by @zonebattler at https://wordpress.org/support/topic/great-little-tool-4?replies=11#post-8603855

Adding new quotes doesn’t work anymore on first try: If you save a new quote, it’s content is lost. However, if you edit the new (but empty) quote, saving it again works fine. So it is still possible to add new data, but it would be appreciated if you could fix the issue.

here’s my detailed bug report. As I wrote in my very first post above, hava a look at my blog at

http://www.zonebattler.net/

and scroll down the sidebar: You’ll notice a column of four randomly chosen photos (thumbnails) which are linked to their respective articles. I think that this is a clever way to bring old articles back to the visitor’s attention again. Here is an example of one of the “quotes” I use:

<a href="http://www.zonebattler.net/2016/06/28/sommerliches-stockholm/"><img src="http://www.zonebattler.net/wp-content/uploads/2016/06/2016-06-28_stockholm-2.jpg" width="150" height="200" alt="Impressionen aus Stockholm" title="Impressionen aus Stockholm" /></a>

Adding a quote like this doesn’t work on first try: Actually, the new quote is created upon saving, but it is empty and does not contain a single character anymore. However, I’m able to edit the new quote, paste in the code snipped as shown above once again and save it a second time. Then it works and the new quote is active, usable and working.

This strange behaviour came up with one of the last plugin updates. It worked well “in the old times” without any issues for years!
