For anyone reading / tracking this issue: it was confirmed as a bug in Angular itself (based on my issue report, see: https://github.com/angular/angular/issues/14872). The bug itself was already fixed in master branch of Angular via https://github.com/angular/angular/commit/ba4b6f58d9cae50e299ddec17ca6849f1de5b6ff and the fix will be part of the next Angular release (4.0.0-rc.3).

I’m going to close this issue here as:

• there are no actionable steps remaining (bug is in Angular and is fixed already)
• there is an easy work-around (don’t use debug mode but run you app in the production mode instead).
