SfPdfViewer crash on iOS

[Yuri Moiseyenko]

I have a relatively simple application that has master-detail form type navigation that contains a list of pdf documents. When I select a document I open it with the sfPdfViewer embedded into the page. The application displays the modal form at the start and then navigates to the master detail page. So the navigation logic is like this:

Root Page -> open Doc List page -> open modal dialog -> close modal dialog -> select document -> open pdf viewer page

It works perfectly fine for the first time in iOS and works all the time in Android,however when I try to go through the cycle again in the iOS or even when I try to go like this:

Root Page -> open DocList page -> open modal dialog -> close modal dialog -> navigate to another page -> open DocList page -> open modal dialog -> close modal dialog-> open pdf viewer page it crashes with the message:

Objective-C exception thrown.  Name: NSInternalInconsistencyException Reason: There can only be one UIMenuController instance.

I isolated it to the PDF viewer component. I'm also using SfListView component and it works fine.
I'm using VisualStudio for Mac, the emulator is on  iOS 11 and I've just upgrade the sfPdfViewer component to the latest version 15.3.0.33

I'm seeing the same issue and tracked it down to the SfPdrViewer also, any chance I can see the solution?
