Issue with HTML code block

Hi community, first time using the code block in Rise as I've been asked to incorporate a "Whiteboard interactive cavas" so I've developed one.

My initial reaction was to use Storyline and add it as a web-object which is working great!

Then I tried the HTML code block and having 2 issues that I would like some support.

1. The HTML height is looking very narrow in rise  

2. HTML shortcuts are not working (shortcuts don't work neither when using SL web object)

 

When testing the HTML file, everything works perfect, both shortcuts and canvas size is 100% so it occupies its full screen.

Any thoughts? 

Attaching an image so you can see how thing the asset looks.

Thanks for your support and guidance.
