AA0248 in Pageextensions not working as expected

[stephanweidmann]

1. Describe the bug
AA0248 is shown hidden with 3 dots for a variable, but if you follow the instructions and add the this, AL0847 occurres (Page MainPage does not contain a definition for variable)
2. To Reproduce

1. Create a page extension with a variable of type boolean, and add a field with enabled = Variable.
   

pageextension 74791 "KVSDMSADVDemo" extends "Company Information"
{
layout
{
addfirst(General)
{
field(KVSDMSADVPREBaseCalendarCode; Rec."Base Calendar Code")
{
ApplicationArea = All;
Visible = Variable;
Enabled = this.Variable;
}
}
}

var
    Variable: Boolean;

trigger OnOpenPage()
begin
    Variable := false
end;

}

3. Expected behavior
No (hidden) warning, or this for pageextension variable

4. Actual behavior
Wrong warning, or unsupported this in pageextension

The same problem happens in tableextension in combination with local procedures/global variables on the tableextension level.
