Race condition in NavigationPage push & pop

[programmation]

Hi all, I have an issue in an app I'm making with Fabulous. I think it's related to a known problem, but I'm not sure if my instance of it is different enough to make it a separate bug.

I have a list of pages that I want my NavigationPage to show. When I put a new item in the list, the page shows up, but sometimes the NavigationPage goes on a push spree and pushes lots of pages (usually the same page). This looks very much to me like a race condition.

Before I try and create a repro, is this something that others have experienced as well?

Might be related to fabulous-dev/Fabulous#158
Xamarin.Forms only updates the number of pages after the push/pop animation is done, whereas Fabulous is fully synchronous.
So there's a mix-match happening where Fabulous thinks XF did not take it account the push/pop and keeps asking it until it's done.

Like I said on the issue, this will need a deep change in the architecture of Fabulous to fix.
Meanwhile you can use the workaround provided.

I think I must be doing something wrong then. I've implemented (an adaptation of) the workaround, but I've still got the problem.
