carriage return in notes not working

[shauryashaurya]

As always betterfountain is wonderful to use.
Thank you!

I recently ran into an issue and wanted to bring it to your attention
(I can try my hand at a pull req if am able to figure out where/how to fix this - your guidance would be very welcome here)

A single line note works perfectly, however a multi-line note (carriage return) does not.
for e.g.,
[[This note works perfectly]]

but

[[This is
not recognized
as

a
note]]

Per the specification, carriage returns are supported in notes.

Thanks again for all your work! So awesome! :)

Seems like I accidentally created a duplicate in #172
unsure what's going on here.
