Start a new article in Joomla JCE Editor. (Same issue in free verion and Pro).
Place some content in it successively:
text
twitter message.
text
twitter message
text
The embed code for the Twitter messages can be retrieved by clicking on the three dots next to a Twitter message and then choosing embed message.
Everything still looks good in the JCE article editor.
But if you click on the Preview tab, the entire order of text and Twitter messages is mixed up.
But if you save the article and publish it online, everything is as expected again.
Why does the preview get messy? Is it a bug or am I doing something wrong?
