Sankey node tooltip has invalid html <br> tag instead of \n

[mac471]

First, this is a great package! Thanks for putting it together!

For the tooltips on sankey nodes (rect objects), the text uses <br> to signify a new line when I believe it should be using \n instead.

Is this something that can get fixed in the next release?

I think there is an open pull request that attempts to address this #130. Any help with that would be great.

Thanks for your note and for pointing me in the direction of the post where
this was also raised. I didn¹t realize that this was a Mac/Windows issue as
well.

I¹ll take a look at ivot¹s solution when I have a moment and will see if I
can help.

Great, thanks.

I have this issue, too (on Linux with Chromium). Note that for the edges, it is still '\n' (line 173, which works for me), and just for nodes it's <br> (line 184, which shows up as <br> for me).

I made a new tiny PR for this issue #152
