Soundcloud embeds in block editor

When using the soundcloud embed with the block editor, the player does not show. There is only a line of a few pixels being shown and when I set

.wp-embed-responsive .wp-block-embed__wrapper iframe{height: auto !important;}

the player never gets to full height, but the wrapper flows over any content above and below.

To confirm it’s a theme issue, I did a live preview with the Twenty Nineteen theme and player shows as intended.

Only through a classic block, the theme shows the player as it should.
