Environment

Describe your dev environment here, giving as many details as possible. If you have them, make sure to include:

• Unity Editor Version: 2019.2.17f1
• Unity SDK Version: 7.19.2
• Installation Platform & Verison: iOS 10 & Android 9

Goals

The goal is to use Game requests (FB.AppRequest function call) friend selector dialog box to send a request to a particular friend. If the friend is not in the suggested friends list, the user should be able to search for the friend and choose him/her. This works when I use no filter, but doesn't work when I'm using the "app_non_users" filter.

Expected Results

When I search for a friend's name, the list below should filter according to my search keyword, everytime I add/delete a letter from the keyword. This filtering should work even when the "app_non_users" filter is used when making the FB.AppRequest() call. Note- This used to work in older versions of the SDK, when the friend selector was shown in a popup box displayed on top of the main app.

Actual Results

The Suggested friends list does not change, nothing happens in this list when I type any friend's name.

Steps to Reproduce

1. Create a new Unity project and add Facebook SDK.
2. Add an invite button, which on click will call the FB.AppRequest(), with "to" field as null, "filters" set to "app_non_users".
3. Deploy on Android or iOS, login to FB, then click the invite button to open the dialog box.
4. Search for a friend's name in the dialog. Nothing happens. Expected- List filters with every letter added/deleted.
