Fix inlineEditor dirty detection with hasRawValue.
When hasRawValue is true, and the current value has any otherwise

HTML-escapable content, the field would always be dirty after any key

press. Simply moving the cursor would mark it as dirty.
We now only htmlEncode the current value if hasRawValue is false.

Moved the cursor around my Markdown document, which had a for loop in it

(and thus a "<"). It didn't ask me to confirm when I hit Escape.
Entered some new text and hit Escape, and it did ask me to confirm.
