sqlflow | Brings SQL and AI | Machine Learning library

I am trying to use Selenium to enter SQL code into a Code Mirror textbox. I'll use the site http://www.gudusoft.com/sqlflow/#/ as an example for the purposes of this question.

My Problem:

I am unable to submit MSSQL SQL code into the code text box if the code contains a carriage return or line feed.

As a work around, I am removing all of them before writing it to the textbox using a JavaScript function but the end result is very ugly word-wrapped SQL.

I've also tried using the SendKeys method on a Selenium webElement object to send the code into the textbox, but I am unsure which element to "Find." Using SendKeys requires that the textbox be selected and when I try to invoke the Click" and "SendKeys" method on that object, I often get a error that the element does not permit user interaction.

If I could consistently find an element that I could interact with, like a TextArea, I would try to paste the contents of my clipboard into it rather than send a very large number of keystrokes to the textbox. For example, the following usually gives me the "unable to interact with this object" error but occasionally works, depending on the current content of the textbox, presumably.
