SelectAll Linux error

[Igor Antić]

I use Lazarus 1.4.4 on Windows 7 and Linux Mint 17.3 Rosa all graphic environments (CINNAMON, MATE, etc.).
I have a simple project with one Unit1 and two components TJLabeledIntegerEdit and TLabeledEdit on the same project. On TJLabeledIntegerEdit I have OnExit event following structures

Tfrm_1.JLabeledIntegerEdit1Exit procedure (Sender: TObject);
begin
  If (JLabeledIntegerEdit1.Text = '') or (JLabeledIntegerEdit1.Text = '0')
  then begin
    JLabeledIntegerEdit1.SetFocus;
    JLabeledIntegerEdit1.SelectAll;
  end;
end;

When  I press TAB and value of TJLabeledIntegerEdit is 0, same procedure in Windows give me:

Linux:

In fact, in Linux when i continue entering the numbers 0 remains at the end, and I get number 1230

while Windows overwritten 0 and get the number 123

I managed to get to solutions in Linux, by chance, in a somewhat unusual way. If I add ShowMessage in procedure and code looks like this

Tfrm_1.JLabeledIntegerEdit1Exit procedure (Sender: TObject);
begin
  If (JLabeledIntegerEdit1.Text = '') or (JLabeledIntegerEdit1.Text = '0')
  then begin
    ShowMessage ( 'Heloo!');
    JLabeledIntegerEdit1.SetFocus;
    JLabeledIntegerEdit1.SelectAll;
  end;
end;
after show message

I press Enter or click the mouse get:

which is identical as in Windows.
How can i achieve in Linux the same result as in Windows without ShowMessage.

Another problem I noticed is that when I entered the TJLabeledIntegerEdit fact i am in EDIT mode with the cursor blinking at the end or beginning of the value

and press CTRL + A

not select me all TJLabeledIntegerEdit in Linux while in Windows selects all
