Basically i wanted to evaluate the integration of TinyMCE and Angular2 based on these tutorials:
https://www.tinymce.com/docs/integrations/angular2/
https://www.ephox.com/blog/angular-2-and-tinymce/

What i observed is:

1. i have an application that works correctly (i am sure, i tested)
2. run "ng serve"
3. at webpack compile state, it fails to find tinymce module and complains. ng cli remains in watching state
4. go to an editor, and break a binding in an angular template by mistyping something
5. it compiles now! (weird behavior 1) - compiles, but of course, doesn't work properly in the browser
6. go back to the editor and undo the changes
7. the previously not compilable code compiles now and works as intended! (weird behavior 2)

OS?

Mac OSX Sierra

Repro steps.

Created a git repo which demonstrates the problem:
https://github.com/legezam/angular-cli-error

1. ng serve the project (at commit 22d71dc7668bebb71a658aa22a3cd83e55841c2e - "Init")
2. observe that webpack fails to compile with the error below. Leave it in watch mode
3. break a binding in 'src/app/app.component.html' (8af4184cfb3a1f0881b1d3cb08fca1831a78a93c - "break it")
4. observe that it compiles the code now and doesn't complain for missing tinymce module
5. undo the last change and save
6. observe that the code that was not compiling at point 1. is being compiled now. on top of that, it works perfectly. (ebe11ccc437ed1dce53443e770846c0d9be6f9d8 - "fix again")

The log given by the failure.

Please help me :)
Many thanks.
