Placeholders cutting up on IOS (entry with Custom font)

Question

Im using custom fonts on my app. However texts up sides are getting cut on IOS.I fixed it on "Labels" with setting "Line Height" to (1.2).But Placeholders are still cutting.How can i fix it?

This is my frame box.

    <ContentView.Content>
    <StackLayout>
        <views:CustomShadowFrame x:Name="FrameBox" Style="{StaticResource CustomizableEntryFrame}" Padding="0">
            <Grid ColumnSpacing="0">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="{Binding ImageColumnWidth,Source={x:Reference View}}"></ColumnDefinition>
                    <ColumnDefinition Width="*"></ColumnDefinition>
                </Grid.ColumnDefinitions>
                <Image Grid.Column="0" Source="{Binding ImageSource,Source={x:Reference View}}" Style="{StaticResource CustomizableImageButtonImage}" ></Image>
                <Entry Grid.Column="1" x:Name="EntryValue"  Text="{Binding TextValue,Source={x:Reference View}}"
                       Style="{StaticResource CustomizableEntryEntry}"
