MAUI 9 Shell Tabbar overrides tabbar title with page title.

[SorenBech2]

Description

When a page is pushed to the stack from a 5th menu point (or more) in a Tabbar, it is not possible to add another page to the stack. No exceptions, no errors - execution just stops! When "go back" is pushed, the label in tabbar is overwritten with the name of the page when returned to mainpage! If the same page is pushed (GotoAsync()) from a menu point 1-4 on the tabbar no issue. The issue exist on IOS, not on Android nor Windows.

Steps to Reproduce

Use attached repro. Deploy on IOS and select a Tab "Working 1". Press "Go to second page"., then press "Go back". Everything works fine.
Select Tab "Not working 1". Press "Go to second page" Nothing happens. The press < More. Observer Tab label has changed from "not working 1" to SecondPage.
