Navigation stops work after chunk load failure

[iiiyx]

I'm submitting a bug report

• Library Version:
  1.5.0

Please tell us about your environment:

• Operating System:
  Windows 10

• Node Version:
  8.11.1

• NPM Version:
  5.6.0

• JSPM OR Webpack AND Version
  webpack 4.6.0

• Browser:
  Chrome 66

• Language:
  ESNext

Precondition and steps to reproduce:

1. Use code splitting: PLATFORM.moduleName(moduleId1, chunkName1), PLATFORM.moduleName(moduleId2, chunkName2), PLATFORM.moduleName(moduleId3, chunkName3)
2. Configure router to use separate routes to modules (chunks)
3. Block chunk2 from loading at Chrome dev-tools
4. Navigate to blocked chunk2 route using a.href or Router.navigate
5. Navigate to good chunk3 route using a.href or Router.navigate

Current behavior:
Any navigation is not working at all after step 3.

Expected/desired behavior:
Navigation to good chunks' routes should work

Stack trace for step 3:

this.Router.isNavigating gets stuck in the true value
Neither router:navigation:complete nor router:navigation:error events arised.

Is there an update on this?
I have the same problem for v1.7.1.

We are focusing our effort on v2, also this issue is a bit difficult to work on at the moment, as v1 router may need some more tests to cover the regression that may be introduced if we are to add a module loading failure recovery code.
