How to remove the important white space at the bottom of a Rise Embed block ?

Hello Everyone,

I have created a Rise Embed block, using these settings :

• <iframe width="100%" height="1074" src="https://www.wikipedia.org"></iframe>
• Padding Top    = No padding
• Padding Bottom = No padding
• Embed Width    = Full Width
• Border         = Unchecked

Then below, I have created a Rise Continue block, using these settings :

• Padding Top    = No padding
• Padding Bottom = No padding

When I preview the course, the iframe has a resulting height of 2209 px.
But it should have a height of 1074 px, as specified in the previous settings.

There is a white space between the Wikipedia page and the Rise Continue block.
This white space is 1135 px high (= 2209-1074), therefore it is an important waste.

How to remove the important white space at the bottom of a Rise Embed block, in order to avoid the waste of space ?

Note: I have checked the heights, using the Web Inspectors of Safari & Chrome.
Note: The Wikipedia URL is an example, and the entire page is 1074 px high.

Thank you for your help,
