Navigate to a child page, display ContextActions on a ListView, close the child page (navigating back to the parent page) while ContextActions are still being shown. Go to any other ListView on any other page and no ContextActions will ever be shown again. I'm guessing there is only a single instance of the ContextActions menu which is shared across all ListViews, and if its still attached to the page when that page is destroyed then it gets destroyed along with it - just a guess.
Very simple to reproduce, see attached solution.

iPhone 6 with iOS 10.3.1
Windows 10 Enterprise

*** This bug has been marked as a duplicate of bug 55588 ***
Please correct me if I am mistaken, but I don't believe this has been fixed and is noted in the duplicated bug 55588 above:
According to that bug, this is suppose to be fixed in Pull Request 885:
And according to that pull request it was released in version 188.8.131.52-pre3:
I have downloaded that "fixed" version 184.108.40.206-pre3 from nuget into my project, built and run my app, I still experience the above issue/bug.
Please let me know if I am missing a step and how I can then properly test that this has fixed my bug; otherwise I ask you please re-open my bug.
