Comrak round-trip introduces extraneous space in code fence info string #685
Description
Description
When comrak is used to parse, and then re-render, a Markdown file (i.e. a round-trip), any code fences in the input are modified such that, on the re-render, each of their info strings will contain an extra leading space space.
Example input:
```lua some_more_info
print("hello world")
```Expected output:
```lua some_more_info
print("hello world")
```Actual output:
``` lua some_more_info
print("hello world")
```Steps to reproduce
Clone this test repo and run cargo test.
Please let me know if further information is required, or if I missed something in the docs. Cheers!
