Displaying via iframes

Hello!

I write with a problem, which I found last time. All of our music sheets are presented via Digital Library which are displayed by "iframe". Most of thees iframes includes links

e.g. https://musescore.com/wroclaw_university_library/wiegenlied-ai-aien.

We decide to include link for this view, to give a possibility for users to download, print or share functions. Unfortunately for some time this links are not displaying via iframe. I have a favor to ask to check this case and if it possible, restoration of the recently available option of presenting a link variant via iframe, as in the example above.

Regards
