Escape sequences break font-locking in double quoted strings

Here's a simple example:

"Hello.\n"

@bbatsov What exactly breaks here? Can you provide a screenshot?

Sure:

@bbatsov Now I noticed this, too, but I don't know what's causing this. It's rather strange. Notably, when you delete dfdfdfdfdf and re-insert it, the fontification will be correct.

As far as Puppet Mode is concerned, everything seems fine: Our special text properties are deleted, so the subsequent text isn't part of the escape anymore.

However, the face property somehow persists. It looks like font lock mode doesn't re-fontify the subsequent text…

It seems this have been fixed. I cannot reproduce using latest puppet-mode.

Tested using emacs 24.5 and 25.2 (on CentOS 6 and Ubuntu 17.10 respectively).
