Hi!
I have a problem with MultiWindowService. My Angular app structure is like this:

• A: my own NPM package which is an Angular module (with component that uses GL and service) with
  imports: [ ... GoldenLayoutModule ]
  (no .forRoot(componentTypes) because i'm not using any declared component)

• B: Angular app with 2 lazy modules. Let's say their names are B1, B2.

  • B1 is a module that imports A and uses its component
  • B2 is a module that uses GL in it's own components and
    imports: [ ... GoldenLayoutModule.forRoot(componentTypes), ]

When i open app and navigate to B1 or B2 everything works fine. Problem appears when i open one of them and later navigate to the other one. The error is:
Error: MultiWindowService(): uniqueName _gl__PluginURLProvider already taken by function PluginURLProvider() ... at ngx-golden-layout.js:59.
It seems like GL wants to initialize something that is already initialized. I don't know if i'm doing something wrong or it is a bug. Maybe app structure is bad but i don't know how to solve this... Has anyone had such a problem?
