A custom icon appears three times after publishing a post instead of normal appearing, as before.
In this particular case, while trying to figure out what's wrong and checking a newly created custom link in 'Text" mode, I can see that closing tag sits in the second line of code:
<a class="html-link" href="http://www.google.com">just testing </a>
After manually moving the closing tag in one line:
<a class="html-link" href="http://www.google.com">just testing</a>
and publishing, two extra icons disappear.
One more thing: the first custom link goes without a problem but the second and the next ones give those triple icons, as described above.
