When quoting a reply that contains a heading, the heading syntax gets rendered as plain text. This is presumably caused by the leading space. Note below that even when stripping spaces manually, ## still gets interpreted wrongly if a bullet list follows.
Example text.
== heading
- Foo
## heading
- Foo
Quoted (default):
Example text.
== heading
- Foo.
## heading
- Foo.
> > Example text. > > == `==` heading == > > * Foo. > > ## `##` heading > > * Foo.
Quoted (strip leading spaces on headings):
Example text.
== header
- Foo.
- ## header
- Foo.
Quoted (strip all leading spaces):
Example text.
== header
- Foo.
## header
- Foo.
