Windows form to be shown topmost from taskbar - vb.net

Question

Using VB.NET I create a form with TopMost=True, FormBorderStyle=FixedDialog, ControlBox=False, text="", size 400x50.
I display this form above Windows 10 taskbar. When I click on the taskbar, the form occupies only a taskbar's portion, the form is moved behind the taskbar. The form remains topmost if it is moved on the working area of the screen.
Is there a way to keep the form topmost above Windows 10 taskbar?
Sample code is given below. Using the arrows keys the form can be relocated for testing.
***UPDATE sample code added.
Public Class Form1
Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
Dim istep As Integer = 1
If e.Alt Then istep = 10
Select Case e.KeyCode
Case Keys.Down
Me.Top += istep
Case Keys.Up
Me.Top -= istep
Case Keys.Left
Me.Left -= istep
Case Keys.Right
Me.Left += istep
End Select
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
Dim b As Rectangle = My.Computer.Screen.Bounds
Dim w As Rectangle = My.Computer.Screen.WorkingArea
Me.Top = w.Height
Me.Left = 500
End Sub
End Class

You can resize the dialog manually according to the screen size in the Load function of the form.
The code would look something like (posting c# code):
Location = new Point(0, 0);
TopMost = true;
var screen = Screen.FromHandle(Handle);
Size = new Size(screen.Bounds.Width, screen.Bounds.Height);
