Android Web view crashes on clicking drop down view in Oreo and Pie devices

I'm loading a URL to my android application web view. The loading procedure is pretty straightforward and is working on all devices from Android Naugat to older ones.

mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl("URL");

<WebView xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"
         android:id="@+id/compare_plans_webview"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         tools:context="com.maximus.enrollment.fragments.ComparePlansWebView">

    <include
        android:id="@+id/loading"
        layout="@layout/basic_loading"
        android:visibility="gone"/>

</WebView>

But the application crashes when I click on a drop-down view within the web view with the following stack trace on Android Oreo and Pie devices,

W/ResourceType: Invalid package identifier when getting bag for resource number 0x020a0172

Extra info:

1. Setting custom font in App Theme
2. I'm overriding getText and getString using a custom ContextWrapper
