[iOS] Double dash converts into a single long dash on after 20584 fix

[MichaelShapiro]

Description

I originally submitted a bug where a double dash in an Entry caused a crash on iOS #20439. It as fixed by #20584 in MAUI 8.0.10.

I believe there is still a bug in that fix unfortunately. The reproduction steps are identical as in the original report.

There is a page (PageN) that hosts an Entry with a Text property set in xaml to double dash.

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="DoubleDashCrash.DoubleDashCrashPage"
             Title="Double Dash Crash Page">

    <Editor
        Text="--"
        BackgroundColor="Yellow"
        VerticalOptions="Center" 
        HorizontalOptions="Center" />
    
</ContentPage>

If you do not tap inside the Entry in step 1 above before visiting PageN then the Entry does correctly reflect double dash (two dashes).

Steps to Reproduce

Before visiting the above page you land on another page (PageA) that also hosts an Entry.

1. Land on PageA. Tap inside the entry. Just tap, no need to type anything
2. Now visit PageN.

Expected result: the Entry reflects the text that was set in xamls above, which is double dash
Actual (bug): The entry reflects a single long dash.
