Rise360 Embed iframe code automatically modified

Just wondering if this issue has been resolved whereby Rise360 automatically streamlines all embed codes - in my case the code removes an essential id that is used to reference my H5P object (url src intentionally modified for this discussion) :

From this :
<iframe src="https://..." name="h5player" width="1466" height="882"
   allowfullscreen="allowfullscreen" class="h5p-player w-100 border-0"
   style="height: 0px;" id="673de457b4df9673de457b4dfa1-h5player"></iframe>

To this:
<iframe src="https://..." name="h5player" width="1466" height="882" allowfullscreen="allowfullscreen"></iframe>

I've read about workarounds using StorylineBlocks but this doesn't work with long iframe embed codes.

Any hope?
