Some options not setting correctly

[JHaller27]

I have some options set with $showdownProvider.setOption('<property>', true);. Some of them work, some act as though the option is not being set. (Have not tested extensively, so these are only the options I'm using).

Broken

Option: setOption('underline', true);

Markdown

__text__

Expected Underlined "text" (does not display in GitHub)

Actual "text"

---

Option: setOption('simpleLineBreaks', true);

Markdown

text
text

Expected "text text"

Actual "text text"

Working

(For sanity check purposes)

Option: setOption('tables', true);

Markdown

| Header1 | Header2 |
|:-------:|:-------:|
| itemA1  | itemA2  |
| itemB1  | itemB2  |

Result

Header1	Header2
itemA1	itemA2
itemB1	itemB2

---

Option: setOption('headerLevelStart', 2);

Markdown

# I'm a heading

Result (html)

<h2>I'm a heading</h2>

I think this could be happening when sanitize is enabled.

Do you confirm that you are using it @JHaller27 ?
