Summary
Liferay's portlet configuration export functionality allows for an Export Permissions toggle. The problem is that when we configure a portlet's permissions, export the portlet configuration with Export Permissions toggled to YES, when we import the LAR file into a new site, the permissions from the original portlet are not transferred.

Steps to Reproduce

1. Start up a new Liferay environment
2. Sign in as [e-mail]
3. On the top of the Welcome page, locate the Search portlet, and click on the hamburger menu > Go into Permissions
4. In the Permissions panel, grant View permissions for all of the OOTB roles, then Save.
5. Back in the Search portlet's hamburger menu > click on Export / Import
6. Ensure that under Application "Configuration" is selected, and under "Permissions" Export Permissions is set to YES
7. Export
8. Save the LAR file
9. Create a new Site (Control Panel > Sites > Sites > Add Blank site)
10. Add a new public page to the newly created site, then go to the newly created public page
11. Identify the Search portlet on the new page in the top right hand corner > Hamburger icon > Export / Import
12. Click on the Import tab
13. Drop in the LAR file saved from the old site, wait until it finishes uploading, then click Continue > Using the default settings but under "Permissions" set "Import Permissions" to YES > click Import
14. After the import completes, click on the hamburger icon > Permissions and check to see if all of the roles' view permissions have been preserved from the import

Actual Result
Even though the portlet data export was configured to export permissions, the default permissions are set on the new site's portlet. This means that the permissions were not properly exported or imported.

Expected Result
The permissions on the new site's portlet should reflect the previous site's portlet permissions.
