Unable to use custom CA with WebView on Android simulator

Bug description: In our testing environment we use certs we sign with our own CA certificate. I was able to successfully install our CA cert on iOS and visit pages in the react native WebView without issue. On the Android Emulator I still get an error even after installing the customer CA. I know it is working and installed, because Chrome uses the CA and honors it, but when attempting to visit the page through the WebView I get the following:

Error loading page
Domain: undefined
Error Code: 3
Description: SSL error: The certificate authority is not trusted

To Reproduce: Setup a simple app with a WebView, open the app and point the WebView at a page with a ssl cert signed with the custom CA cert.

Expected behavior: The custom CA should be used and the error should not appear.

Environment:

• OS: macOS
• OS version: 11.5.2
• react-native version: 17.0.2
• react-native-webview version: 11.13.0
• Android emulator info: sdk_gphone_x86-userdebug 10 QSR1.210802.001 7603624 dev-keys

That’s would allow for testing, but if does address the fact that if a CA has been added there shouldn’t be an error thrown when accessing urls signed with that CA.
