looks like this isn't just the case for codeblocks. indented blocks never seem to be formatted at all.

another use case i encountered is content tabs with tables in them:

| a | b        |
| - | -------- |
| a | asdfasdf |

=== "foo"

    |a|b|
    |-|-|
    |a|asdfasdf|

=== "bar"

    |a|b|
    |-|-|
    |a|asdfasdf|
