[Bug]: Blob field upload and OnValidate

Please include the following with each issue:

1. Describe the bug
If there is post-processing (OnValidate) with a message or notification for a blob field in OnValidate, the upload window is no longer closed and remains open on the page.

2. To Reproduce
Field in a Table extension:

tableextension 50100 MyCompanyInformationExt extends "Company Information"
{
    fields
    {
        field(50100; "New Company Picture"; Blob)
        {
            Caption = 'New Company Picture';
            Subtype = Bitmap;
            ToolTip = 'New Company Picture.';
            trigger OnValidate()
            begin
                Message('My Onw Company Picture has been uploaded.');
            end;
        }
    }
}

Page Extension:

pageextension 50100 MyCompany extends "Company Information"
{
    layout
    {
        addlast(General)
        {
            field(MyMyOnwCompanyPicture; Rec."New Company Picture")
            {
                ApplicationArea = All;
                Caption = 'My New Company Picture';
                Editable = true;
                ToolTip = 'Specifies my own company picture.';
            }
        }
    }
}

3. Expected behavior
The Upload should close, the message should appear

5. Versions:

• AL Language: 16.2.1869542
• Visual Studio Code: 1.105.1
• Business Central: (Platform 27.0.40210.0 + Application 27.0.38460.40293)

Internal work item: AB#612421

Reproduce the issue with the provided AL table and page extension in Business Central Platform 27.0 using Visual Studio Code. Start with the Blob field's OnValidate trigger and upload interaction; done means the upload window closes while the validation message appears.
