The problem is that org.openide.text.DataEditorSupport.messageHtmlName performs
some I/O in EDT. Unfortunately, this method has to be blocking, and has to be
called in EDT.

I've prepared a patch that uses the last computed (or default) data to compute
the result, and then checks (in background) that the result was correct.
If the result was incorrect, it updates titles of the editor tabs.

I'm not sure that the messageHtmlName method is used only to get editor tab titles.
If there is some other place that calls this method, and that is not updated by
CloneableEditorSupport.updateTitles, the patch is wrong.

Reassigning to platform/Text. Mila, please evaluate the bug.
Thank you.
