Freezing App when Navigating Between Tabs with BlazorWebView in Maui Blazor App

[alzubitariq]

Description

Two Tabs: an AppShell page that contains two tabs named "page1" and "page2". These tabs likely represent different sections or functionalities within the app.

Navigation from Page1 to Another Page: When navigate from "page1" to another page, presumably using some kind of navigation mechanism like a button click or a navigation service.

BlazorWebView Content: The page you navigate to from "page1" contains a BlazorWebView component.

Tab Switching: After navigating to the page containing the BlazorWebView, you switch tabs from "page1" back to "page2" and then "page2" back to "page1".

App Freeze: At this point, when you switch back to "page1" after previously navigating away from it, the app freezes. This means that the app becomes unresponsive and does not react to user input or continue executing code.

Steps to Reproduce

Create new maui blazor app
