Winforms - Control.ResetBindings() summary seems incorrect?

Right now the xml summary for `Control.ResetBindings` reads:

```csharp
Causes a control bound to the to reread all the items in the list and refresh their displayed values.
```

[Docs](https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.control.resetbindings?view=netframework-4.7.2#System_Windows_Forms_Control_ResetBindings) - [Control.xml](https://github.com/dotnet/dotnet-api-docs/blob/master/xml/System.Windows.Forms/Control.xml)

The implementation clears all the bindings though:

```csharp
public void ResetBindings() {
ControlBindingsCollection bindings = (ControlBindingsCollection)Properties.GetObject(PropBindings);
if (bindings != null) {
bindings.Clear();
}
}
```

I think perhaps this summary was copied from `BindingSource`? ([Docs](https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.bindingsource.resetbindings?view=netframework-4.7.2#System_Windows_Forms_BindingSource_ResetBindings_System_Boolean_))

Start in xml/System.Windows.Forms/Control.xml and compare the Control.ResetBindings implementation in the linked Control.cs source. Confirm the documented behavior against the implementation, then update the XML summary and verify the resulting API documentation.
