Hello,
JCE 2.8.3, Joomla! 3.9.14
we have as example the following in some articles:
<a class="label label-info" href="https://www.joomlacontenteditor.net/index.php?option=com_content&view=article&id=22681:apogee-kuendigt-das-neue-symphony-desktop-an&catid=45&lang=de-DE">weiter </a>
After changing the href="https://www.joomlacontenteditor.net/..." with the anchor button of the editor in Editor mode,
class="label label-info"
becomes
class="label, label-info"
so none of that two classes can be interpreted by browsers, because JCE changes "label label-info" to "label, label-info"
there has to be no "," between classes!
Can you please investigate that and fix that bug as soon as possible?
