Steps to Reproduce

NavigationIssue.zip

Download the attached project NavigationIssue.zip or clone it from https://github.com/MaxFelinger/dotNETMAUI_NavigationIssueWithTabChange
Open the attached project
Select TabItem3
Click the button "GoTo RegularPage" to navigate to "RegularPage"
Select TabItem2
Click the button "GoTo //TabItem3/ModalPage"

Actual outcome:

Target modal page pops up and immediately moves away so that we end up seeing TabItem2 selected (as before step 5).
When we select TabItem3, we see the ModalPage.

Expected outcome:

ModalPage should be shown. We should stay on the modal page.
TabItem3 should be selected and its root page should be shown after navigating back from ModalPage.

See attached video for more details (description area of this issue).
