onRationaleAccepted and onRationaleDenied implemented in Fragment are not called

Question

When I was implementing the EasyPermissions feature in Fragment, I noticed that these callback functions were not being called, even though I implements EasyPermissions.RationaleCallbacks.

I investigated in the debugger and found the following

Execute EasyPermissions.requestPermissions, passing MainFragment as the host.

PermissionRequest.Builder(host.context) is called. host.context = MainActivity

MainActivity does not implement EasyPermissions.RationaleCallbacks, so onRationaleAccepted and onRationaleDenied will not be called.

Is this the correct behavior? Should EasyPermissions.RationaleCallbacks be implemented only in Activity?

Code

The source code has been uploaded to github. https://github.com/Nunocky/EasyPermissionsStudy

class MainFragment : Fragment(), EasyPermissions.PermissionCallbacks,
    EasyPermissions.RationaleCallbacks {

    private val requiredPermissions = listOf(
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.CAMERA,
    )
...

    override fun onResume() {
        super.onResume()
        checkPermissions()
    }

    private fun checkPermissions() {
        if (!EasyPermissions.hasPermissions(
                requireContext(),
                *(requiredPermissions.toTypedArray())
            )
        ) {
            // Do not have permissions, request them now
            EasyPermissions.requestPermissions(
                host = this,
                rationale = "permissions required",
                requestCode = REQUEST_PERMISSIONS,
                perms = requiredPermissions.toTypedArray()
            )
        }
    }

...
    // TODO : not called?
    override fun onRationaleAccepted(requestCode: Int) {
        toast("onRationaleAccepted")
    }

    // TODO : not called?
    override fun onRationaleDenied(requestCode: Int) {
        toast("onRationaleDenied")
    }
}

Question

I have try easypermissions-ktx's sample project. When denied SMS(which request permissions from MainFragment.kt), and then allowed it again, MainFragment.kt :: onPermissionGranted was not called. (MainActivity.kt :: onPermissionGranted was called. )

When pass through the rationale dialog, onPermissionGranted in the fragment is not called ?
(Immediately allows the same permission from fragment, then onPermissionGranted in Fragment was called.)

This casting context to Fragment doesn't seem to be succeeding.
