Adding emoji to the Description field resets its value after saving

Hello,
when I try to copy the code of any emoji from https://www.iemoji.com/ or https://emojipedia.org and then paste it into description field + some text and save the post, then after reloading description field is empty. Description tag on the actual page is borrowed directly from the beginning of the article.

Is to possible to fix this in the next update?

Thanks
Michal
