Unable to edit HTML embed content when it renders as zero height

Hi @memetican, thanks for your report, I am not sure if there has a been a change to the embed, I will need to check how that was working before. I will check that and get back to you.

In the meantime, after selecting the embed from the navigator, the embed can be edited from the settings panel:

When I have more info, I will let you know. Thanks in advance.
