Description

I have this xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage
    x:Class="TestFody.Page.SideMenuDemo"
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:xct="http://xamarin.com/schemas/2020/toolkit">

    <xct:SideMenuView>

        <StackLayout
            xct:SideMenuView.MenuWidthPercentage="0.8"
            xct:SideMenuView.Position="LeftMenu"
            BackgroundColor="Blue">
        </StackLayout>

        <StackLayout
            xct:SideMenuView.MenuWidthPercentage="1"
            xct:SideMenuView.Position="RightMenu"
            BackgroundColor="Red">
        </StackLayout>

        <StackLayout xct:SideMenuView.Position="MainView" BackgroundColor="Yellow" />

    </xct:SideMenuView>
</ContentPage>

It should visualize a blu left menu and a red right menu, but it seems is always red

Steps to Reproduce

se above

Expected Behavior

blue side menu on left, red on right

Actual Behavior

red on left and right

Basic Information

• Version with issue: 1.0.2

• Platform Target Frameworks:

Workaround

        <StackLayout
            xct:SideMenuView.MenuWidthPercentage="0.2"
            xct:SideMenuView.Position="RightMenu"
            BackgroundColor="Red">
        </StackLayout>

Seems that using 0.2 in RightMenu's MenuWidthPercentage, it works. Must the two percentages have a total sum of 1?
