- Description

From the docs, method CustomTabsIntent.Builder#enableUrlBarHiding will enable the url bar to hide as the user scrolls down on the page. However, it seems that this behaviour this enable by default when this method is not invoke to the builder.

- Relevant code to trigger the issue.

public static void launchUrl(@NonNull Context context, @NonNull String url) {
    try {
        new CustomTabsIntent.Builder()
                .setToolbarColor(ContextCompat.getColor(context, R.color.primary))
                .setShowTitle(true)
                .build()
                .launchUrl(context, Uri.parse(url));
    } catch (ActivityNotFoundException e) {
        Intents.get(context).openWebBrowser(url);
    }
}


- A screenrecord or screenshots showing the issue (if UI related).

See attached screenshots.  The image of 09:29:27 is after the CustomTabsIntent#launchUrl is invoked, 09:29:39 is after scroll (see that the url bar on the top is now hidden).


- Expected behaviour

If I understand the docs correctly, the url bar on the top should not hidden if CustomTabsIntent.Builder#enableUrlBarHiding is not called.
