I think I'm running up against another bold/italics bug. I did some quick searches and it looks like the other issues were considered resolved, sorry if I'm re-reporting on something already fixed that hasn't made it upstream yet.

Installed from pip current Python-Markdown version 3.0.1

The raw markdown line that breaks is:

This is text **bold *italic bold*** with more text

The output I'm getting is as follows:

<p>This is text <strong>bold *italic bold</strong>* with more text</p>

However, the following format does seem to work correctly.

This is text ***bold italic** italic* more text

The output is

<p>This is text <em><strong>bold italic</strong> italic</em> more text</p>
