Description

When I embed a snippet in a code snippet, restricting the lines to :1:1, the code block is rendered empty. This can temporarily be fixed by writing ::1 (which should be equivalent), so it's not urgent or anything, but I thought, you might want to fix that.

Minimal Reproduction

1. Create the following code block:

--8<-- "some-code-snippet-file-path.pony:1:1"

2. Build your site and check the result for the code block
