IntraText tag adornment disappears when following text is empty

Hi,

In my syntax editor control, a text is structured with 3 parts: a readonly region, an intraText tag and an editable range:

A sample is descirbes in the following link:

When i don't set a value (or empty value), the intraText tag is still defined in the property of editor, but the related adornment is not displayed.

Is it possible to force the tag display when the next range is empty ? and how i can do it ?

Thanks.
