[Android] Duplicate Title Icon Appears When Setting NavigationPage.TitleIconImageSource Multiple Times

[nivetha-nagalingam]

Description

Summary On Android in .NET MAUI, calling NavigationPage.SetTitleIconImageSource(page, "image.png") more than once for the same page results in the icon being rendered multiple times in the navigation bar.

Steps to Reproduce

• Launch app on Android. NavigationPageIssue.zip
• Tap “Set TitleIconImageSource” once: icon appears.
• Tap it again: a second identical icon appears.

Expected Behaviour:

• Calling NavigationPage.SetTitleIconImageSource(page, "dotnet_bot.png") multiple times for the same page should result in only a single toolbar icon.

Actual Behaviour:

• On Android, each repeated call to NavigationPage.SetTitleIconImageSource with the same image adds an additional duplicate icon instead of reusing the existing one
