Export as a Postman Collection removes Variable Value

[SwapnilkumarRane]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

I have created Testing environment and saved a host variable value to the same, but after exporting it in Postman Collection the value for the variable was exported as a null/empty.

.bru file to reproduce the bug

Create Test collection
Add some request and set up host "{{host}}" variable
input host variable in any of the environment created.
Export the collection as a postman collection and look for the variable value
If we import the same Collection it will not import the environment.
