Embedding video from imgur

I’m trying to embed a video from imgur.com.

The code I should insert in my post is the following:

<blockquote class="imgur-embed-pub" lang="en" data-id="a/szygkwP" data-context="false" ><a href="//imgur.com/a/szygkwP">Wacom Desktop Center</a></blockquote><script async src="//s.imgur.com/min/embed.js" charset="utf-8"></script>

But if I try to insert it in my post I don’t get the embedded video, instead I get something like this:

Wacom Desktop Center

How can I solve this problem?
Thank you in advance for your help!
