Unexpected behaviour of heading following executable code block #12440
Description
Bug description
If title is not explicitly set in the yaml frontmatter, the heading immediately following an executable code block (i.e., ```{python}) is used as the title of the document. This bug does not happen when the code block is not executable (i.e., ```python).
Steps to reproduce
| Input | Output |
---
format: typst
---
# This is what happens when I don't set the title.
## This is a level 2 heading
This is some paragraph text.
```{python}
# This is an executable Python code block.
print("This is the output of an executable Python code block.")
```
## This is another level 2 heading
This is some more paragraph text. |
