rich.markdown generates AssertionError rendering certain strings

[jspv]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Moved from here

The following string "| Simple | Table |\n| ------ | -----" or similar ones that are incomplete tables will generate AssertionError rather than printing the string.

from rich.console import Console
from rich.markdown import Markdown

# This will work
responses = "| Simple | Table |\n| ------ | ----- |\n| cell1  | cell2 |"

# This will not work
responses = "| Simple | Table |\n| ------ | ----- "

console = Console()
md = Markdown(responses)
console.print(md)

Results:

Traceback (most recent call last):
