Plot fails to sanitize invalid html strings

[rreusser]

See: https://codepen.io/rsreusser/pen/xLOPGv

Expected behavior:

1. plot is created
2. title is set to invalid string: "failure<sub>2</sub></sub>"
3. plot is restyled to valid string: "success"
4. plot has title "success"

Observed behavior:

As soon as the title is made invalid in step 2, further updates don't work.

Ohhhh, I was being really silly here. It rejects the promise. Switching that to catch makes it succeed. Facepalm. The problem in my real example was that it was in the react pipeline for me and I wasn't really handling errors so that it was react that blew up.

Nonetheless, I don't necessarily see why the svg text utils shouldn't just sanitize the input and do its best.
