Cannot set fsStyle of TBBUTTONINFO struct

[rmeshksar]

Hi,
I am not able to assign a value to fsStyle attribute of TBBUTTONINFO struct.

Is this due to this line?

Vanara/PInvoke/ComCtl32/CommCtrl.Toolbar.cs

Line 3780 in bdf07f1

public ToolbarStyle fsStyle { get => (ToolbarStyle)_fsStyle; set => _fsStyle = (byte)((ushort)fsStyle & 0x00FF); }

Shouldn't it be:

public ToolbarStyle fsStyle { get => (ToolbarStyle)_fsStyle; set => _fsStyle = (byte)((ushort)value & 0x00FF); }

Also, would you mind explaining this logic? What the reason of bitwise operation with 0x00FF?
