I can see the following problem in the latest webapp.
a) I receive an email, I can view it correctly in the preview in my case in the bottom part of the screen
b) I doubleclick on it, and it is brought up in a separate tab, but the text is empty.
c) This appears to be more often when the text of the email contains images.
d) I cannot always replicate it, but it’s definitely happening.
c) It did not happen a few versions before.
