When I create a transactional e-mail via Marketing --> E-Mail Templates and then click "Preview" my preview window is somehow being cut to a preview_iframe which only covers like 1/5th of the full page and I need to scroll in order to see the full e-mail preview.
Does anyone have an idea how and where I can edit this, so e-mail preview is showing on full page?
I found this answer and code : here that worked for me.
Using the Kishan code gives me a screen that says "Email Preview" at the Top, with the Magento copyright info underneath but no template content in 2.3.4. I stumbled across this code on git healthywebsites clintonwere that gave me the result I expected. Hopefully it can help somebody else.
