How to make D2L LTI Advantage iframe automatically vertically scale to available size

Options

When registering an LTI Advantage tool, you can specify a fixed width/height for the iframe to open the link in. A tool can also use postMessage to let D2L know its desired size. However, for a tool with a responsive layout and dynamic content (e.g. a list), there is no fixed size to set. This means that in practice, the iframe will always be either too large, or not optimally large enough.

 

Is there a way to let D2L scale the iframe an LTI Advantage frame to all the available space?

 

I noticed that D2L already ignores the width in certain situations, and uses the full width. Can it do the same for the height?
