Control visibility on navigate pages is not consistently updated accross groups

[nicolassaleron]

Describe the bug In Navigate pages, if the visibility of a group is controlled with a variable, the visibility is only refreshed when the variable value is changed on the displayed tab. If the group is currently hidden (because you are on another tab), when the tab where the group is placed is displayed by the user the visibility might be incorrect.

To Reproduce Steps and to reproduce the behavior:

1. Create a project with the page below
2. Run it and play with the IsChecked checkbox.

page 80000 "DRCVG TEST"
{
    PageType = NavigatePage;
    UsageCategory = Tasks;
    ApplicationArea = All;
    Caption = 'TEST';

    layout
    {
        area(Content)
        {
            group(General)
            {
                Caption = 'General';
                field(IsCheckedControl; IsChecked)
                {
                    ApplicationArea = All;
                    Caption = 'IsChecked';

                    trigger OnValidate()
                    begin
                        UpdateControls();
                    end;
                }
            }
            group(Other)
            {
                Caption = 'Other';
                field(IsCheckedControl2; IsChecked)
                {
                    ApplicationArea = All;
                    Caption = 'IsChecked';

                    trigger OnValidate()
                    begin
                        UpdateControls();
                    end;
                }
                group(AVisibleGroup)
                {
                    Caption = 'AVisible';
                    ShowCaption = false;
                    Visible = AVisible;
                    InstructionalText = 'AVisible';
                }
                group(BVisibleGroup)
                {
                    Caption = 'BVisible';
                    ShowCaption = false;
                    Visible = BVisible;
                    InstructionalText = 'BVisible';
                }
            }
        }
    }

    trigger OnOpenPage()
    begin
        UpdateControls();
    end;

    local procedure UpdateControls()
    begin
        AVisible := IsChecked;
        BVisible := not IsChecked;
    end;

    var
        [InDataSet]
        IsChecked, AVisible, BVisible : Boolean;
}

Expected behavior When the page is loaded BVisibleGroup should be visible and AVisibleGroup should be hidden (because IsChecked is false). When IsChecked is changed on the first tab, the visibility of AVisibleGroup and BVisibleGroup should be consistant when they are displayed again.
