When I am looking at the definition of a class, I can also see the associated examples. Currently when clicking on the eye icon for preview on the Javascript window, only the first example is shown. The rest appear blank. I have just tried this with:

Editing the examples shows that the full text is there.

Thanks for this report, an issue has been opened and should be processed quickly (#858).
This problem is due to a copy/paste carrying unnecessary <span> tags. More extensive monitoring is now in function but some tags may remain, so take care of only copy the plain text (shift+ctrl+v or double copy/paste through a plain text only field).
