After you open an invoice record, the product Subgrid refreshes twice and gives a message: "Loading records"

Repro steps:

- Login to CRM organization
- Goto Sales > Invoices
- Open an existing invoice record with the product records in the sub grid
- The product records  on the Product sub grid gets refreshed Once i.e. displayed twice and displays the message: "Loading records..."and then displays the complete list.
- This also happens when you create a new Invoice record and then add product records through the sub grid.

No error message just a display message "Loading records..."and then displays the complete list.

This issue is reproducible on 8.2.0 as well as 8.2.1 build versions.

It will be great if  there is a code change considered for this issue so that the Product records would not be refreshes twice which might not lead to some performance issues.

Please vote up for implementing this in the future.

Thank you!
