When the

is present in a page, formatting via the "Format" menu in the WYSIWYG editor doesn't work. Often the text will not change, or it will just disappear.

Steps to reproduce:

Add dynamictasklistmacro and text to page
Save page
Edit page again
Select text other than the macro
Go to "Format" menu and click on ANY of the pre-set formats
Bam! Watch it disappear (or do nothing)

The associated JavaScript error (an unhandled exception, actually) occurs in the "TinyMCE.prototype.createFormatNode" function in the zip_src servlet (line 2658). It seems the 2nd attribute for the element (index 1) returns "" as the name and void as the value. The cause is still the macro, though.
