Alert email attached the wrong image

I am using Grafana over Docker. When setting an email alert I get image of the “Home Dashboard” insted of the alert plot. How can I get the right plot?

I have the same issue. It seems to be related to rendering overall - as if I want to create direct link to panel, it gives me homepage image and not panel image.

Did you manage to resolve that at all?
I’m using grafana 7.3.4 with external rendered - both in docker…
