Problems disappear when re-opening editor

Congratulations for the good work.
Scala support in IDEA has improved a lot recently, it is approaching the level of the quality of Java tools. :)

I've discovered, that syntax highlighting is wrong, or some strange error is reported, after some editing.
If I close the editor and reopen again, then everything is ok.

Not a big problem, but a little annoying. :|

s""""......"""" strings a specially problematic.

See screenshot for an example of bad syntax highlighting after the "stripMargin".
