16.02 link inside annotation does not open web page

Since Blend4Web version 16.02 .
Link inside annotation does not open web page.
Clicking on a link just closes the annotation.


test_annotation_link.html

test_annotation_link.blend

HTML Tags are not supported with the Annotation anchor type.
You should use the Custom Element type.

This linking worked at least in 15.09. Why should such a great feature to be removed?
Other tags still worked with 16.02. I tried to put an image inside annotation. Worked with linked image and by inserting base64 image code inside blender
16_2.html
16_2.html.blend

I still have no idea, how HTML Custom Element should work. Am I correct that there is no way to use it when I output just Blend4Web html?

It worked, but was not supported . Annotation type is text-only. In last releases we have changed anchor module code. But we test only plain text..

In the next release we will add (or return ) the link clicking.
