This:
cat <<EOF
one
two
three
EOF
Prints:
one
two
three
And this:
cat <<EOF
one \
two \
three
EOF
Prints:
one
two
three
But while this:
cat <(
cat <<EOF
one
two
three
EOF
)
Prints:
one
two
three
This:
cat <(
cat <<EOF
one \
two \
three
EOF
)
Prints:
one two three
What's going on? Why are the newlines disappearing in this situation?

Similar to What does POSIX require for quoted here documents inside command substitution? (probably the same bug or similar...)

That has been solved in bash 5.0.
