Flags not showing when using a Pathbase

[smarais97]

Expected Behavior

Flag images should show when pathbase is used.

Current Behavior

Currently to flag images are showing on local.
On production server where we use a pathbase for example: "/app", the flag images are not showing.

Local:

Production:

Possible Solution

The pathbase should be included in the URL, in other words it should be something like /app/static/media...
I might be missing something, anyone perhaps know why this would be happening? I do have the pathbase in my react app available but can't see a way to easily let react-intl-tel-input actually use it.

Is there a property where I can set the base URL so that the flag images use the pathbase or how can I fix this?

Kind regards
