Thanks Vlad - this looks great! 💯

Just one problem we should fix before merging: The app crashes when a Popup with an anchor is displayed and while it is currently displayed we navigate away from the page.

Here's two examples demonstrating this using the Sample App:

Looks very well done! Just need to fix that IOS bug and it will be good to merge. The issue was listed previously by the @TheCodeTraveler. Once that is cleared i will be happy to approve this. The look and feel is now consistant across both android and ios.

Changes look. Good I have tested them on IOS and the crash is no longer an issue. Only one minor bug that might be nice to fix before merge.
