Different animation for page enter and page leave will break the back navigation

[NoNameProvided]

Short description of the problem:

When a different animation is used for navigating back than the one was used to push the current page, the animation stuck halfway.

Edit: Most of the time this only happens if I try to pop from the entered page, if I navigate to a third page and pop back using a custom transition, everything works.

What behavior are you expecting?

I can push and pop with any custom transition, and the two is not tied to each other.

Steps to reproduce:

1. Push a page with iOS transition
2. Pop the page with android transition
3. See that the back animation get stucked, half of the screen is black, but the visible part of the parent page is usable.
