html content does not include summary, whereas md content does

[Dieterbe]

What version of Hugo are you using (hugo version)?

current git build (v0.62.0-3-gaa4ccb8a)

$ hugo version
Hugo Static Site Generator v0.63.0-DEV linux/amd64 BuildDate: unknown

Does this issue reproduce with the latest release?

Yes, tested with 0.62.0 official release as well.

can easily be reproduced like so:

mkdir hugo-test
cd hugo-test
hugo new site quickstart && cd quickstart
mkdir themes && cd themes && git clone https://github.com/yanlinlin82/simple-style.git && cd ..
echo 'theme = "simple-style"' >> config.toml
mkdir content/post

cat <<EOF > content/post/mdpost.md
---
title: "Mdpost"
date: 2019-12-30T15:21:57+01:00
draft: false
---
summary
<!--more-->
content
EOF

cat <<EOF > content/post/htmlpost.html
---
title: "Htmlpost"
date: 2019-12-30T15:21:15+01:00
draft: false
---
summary
<!--more-->
content
EOF

hugo server

when you load the html post and the md post in your browser, you can see that the html post does not include the summary, but the markdown does.

Thank you for reporting this. I will check if this is a problem in my theme ('simple-style').

[Dieterbe]

no, the problem is the {{.Content}} variable, sometimes it contains the summary part of the content, sometimes it only contains the part of the content after the summary divider.

Just a note that if we do want to change this behavior, the place to look is in this if block or, if #9423 is merged, in this function.

As it stands now, there is an integration test assertion that HTML content must not include the main content, so the solution might be to document this discrepancy.
