API doc generation broken by angular commit 6fc267f [fix: split dynamic bits in platform-browser...

[naomiblack]

Prior to @IgorMinar's change in angular/angular 6fc267f, API doc generation works.

After, we get this error message during gulp check-deploy and can't build the API docs:

info:    running processor: renderDocsProcessor
error:   Error: Failed to render - doc "@angular/platform-browser/index" (module)  - from file "@angular/platform-browser/index.ts"

Original Error:
