karma coverage html not listing all files in subfolders

version:-
"karma-coverage": "^2.0.1"

settings:-
coverageReporter: {
type : 'html',
dir : 'coverage/'
}

path for source files:-
'../Web/Js/**/*.js': 'coverage',

When running the tests, the coverage is generated:-

But :
This is my coverage folder structure
```
[Coverage]
create-account-management.js.html
index.html
[Account]
--->[Components]
create-account.js.html
index.html

```
The Coverage folder index.html does not have any sub folder java script source links to view coverage.. In my case create-account.js.html cannot be reached from the outer index.html . The outer index.html has only create-account-management.js.html and not the inner folder javascript source files.

I was expecting the index,html to contain create-account.js.html and create-account-management.js.html links

Start with the reported coverageReporter HTML settings and the '../Web/Js/**/*.js' source glob. Reproduce the output, then inspect coverage/index.html alongside the nested Account/Components/index.html and create-account.js.html files. Done means the outer index.html links to coverage files in nested source folders as well as create-account-management.js.html.
