Rise iframe embed issue

I am trying to embed a custom calculator in a Rise course using the Embed block option, and I'm having a very loooooooong problem.  Even though the iframe code defines the height of the item in pixels, the content block is showing as super long.

And when I try pasting just the share URL from the site, it cuts the calculator off!

Here's the code:

<iframe src="https://app.calconic.com/api/embed/calculator/5cfe7dbc0c34ed002687bd19" sandbox="allow-same-origin allow-forms allow-scripts allow-top-navigation allow-popups-to-escape-sandbox allow-popups" title="Calconic_ Calculator" name="Calconic_ Calculator" height="522px" scrolling="no" style="width: 100%; border: 0; outline: none;"></iframe>

Am I doing something wrong?

Thanks!
