<!ENTITY % StyleSheet "CDATA" -- style sheet data -->

https://www.w3.org/TR/html4/types.html#h-6.2:

The first occurrence of the character sequence "</" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.

So it seems that Aquamail is interpreting /> as the end of the CDATA when it should only be interpreting </ as the delimiter.

All of the following render the message correctly:

  • Thunderbird 60.3.3
  • GMail as of 2018-12-25
  • Apple Mail 12.2
