Hi,

Seems there is an issue with word rendering for italic when it is the first word in an item list.
When you add an second space before it (or any chars/words), the rendering becomes fine.

For example, the content below:

all is good: _italic_ or *italic* or __bold__ or **bold**

- **bold** is ok
- __bold__ is ok
- _italic_ is ko
- *italic* is ko
-  *italic* is ok
-  _italic_ is ok

Renders as:

And you can also see this issue on the second example (with toolbar) of your home page with the word "Italic" itself.

Thanks in advance.
