[Enter steps to reproduce:]

1. create a ruby file(.rb)
2. paste x = %r{/assets/}
3. click on that.

ps(guessing): '/' above is literal, but interpreted as indicates of the start and end.

I'm seeing this error even without '/' in the regex. Literally %r{} (which is equivalent to //) starts throwing this error on every keypress within the delimiters.

[TG-KK]

Atom 1.20.0, regex-railroad-diagram 0.19.3, and this is still happening.

Atom 1.19.7, regex-railroad-diagram 0.19.3, happening for me also. Is there likely to be a fix?
