How to Make Span Text/content Wrapped if it exceeds?

Question

Here if my account number exceeds the numbers from last get cut/disappear. So I used LineBreakMode to WordWrap in label but this is also not working here.

                                <Label FontFamily="InterstateRegular">
                                    <Label.FormattedText>
                                        <FormattedString>
                                            <Span Text="{x:Statiresx:AppResources.ACC_NO_COLON}"/>                                               		<Span Text="{Binding AccountNumber}" TextColor="#0098CC"/>
                                        </FormattedString>
                                    </Label.FormattedText>
                                </Label>
