Exporting a text that has a (or some) "\n" (line feed) will loose the text decorations when exporting.

To reproduce do:
Create an "article" with following text in "summary" field:

This text has
an enter <strong>before bold efect</strong>

(Notice, this should be done without (or disabled) ezoe)

Then export, and verify that the bold effect disappeared.
However if you change the <enter> (line feed) to <br/> it works as expected
