iOS 14 App freezes when Visual="Material" in Entries with IsPassword="True"

When you are using Xamarin.Forms.Visual.Material package and create a style like this:

<Style
    TargetType="Entry">
    <Setter
        Property="TextColor"
        Value="{StaticResource OnSurfaceColor}" />
    <Setter
        Property="PlaceholderColor"
        Value="{StaticResource OnSurfaceColor}" />
    <Setter
        Property="BackgroundColor"
        Value="Transparent" />
    <Setter
        Property="FontSize"
        Value="{StaticResource FontSizeNormal}"/>
</Style>

And create a layout like this:

<Frame
        Margin="16,24">
        <StackLayout
            Margin="4,8"
            Spacing="0">

            <Entry
                Visual="Material"
                Text="{Binding UserName}"
                Keyboard="Email"
                Placeholder="{i18n:Translate signIn_txtUserName_placeholder}" />

            <Entry  Visual="Material"
                    x:Name="txtPassword"
                    IsPassword="True"
                    Text="{Binding Password}"
                    Placeholder="{i18n:Translate signIn_txtPassword_placeholder}" />

        </StackLayout>
    </Frame>
