B4J Question Webview problem

[menneaduplo]

If I try to load the simple attached map.html file into a B4J webview this doesn't work.
With any browser, yes.
The html file contains an OpenStreetMap map with scripts.
Can anyone help me?
Thanks in advance.

My Code

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private xui As XUI
    Private Button1 As B4XView
    Private WebView1 As WebView
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("main")
    Dim S As String
    S=File.ReadString(File.DirApp,"map.html")
    WebView1.LoadHtml(S)
    MainForm.Show
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    WebView1.LoadUrl(xui.FileUri("C:\Users\H\Downloads\map.html", ""))
End Sub

I've tested with OpenJDK 14 (download from forum)
