In the text editor, when the content with syntax is pasted, the conversion from markdown to HTML doesn't occur automatically. Instead, the enter key should be hit for each line before conversion.

For example, when I copy the text shown below and paste it to the TinyMCE text editor. Nothing really happens. I have to go through each line of text and hit enter to trigger the conversion.
