Android Webview not rendering the headers of SharePoint page

Workspace one Web Browser which is a secure enterprise browser app is built on Android System WebView, we have an Android WebView in which I am trying to load a SharePoint page. However, certain elements of the page are not being rendered or displayed correctly in the WebView.

The same SharePoint page renders correctly in a Chrome browser, where all the expected elements are visible.

Please refer to the attached image for comparison and reference.

In Chrome 

In Android System Webview based Web Browser (for example Workspace ONE Web)

We mainly wanted to know why is this behaviour specific to Android System WebView based browser.
