@MartinZikmund thanks for pointing it out and creating an issue, have you seen any unexpected behavior ~ a crash or UI glitch with BreadcrumbBar due to incorrect usage of GetFocusedElement?

[MartinZikmund]

@Hemantxk not necessarily, just the current behavior essentially means that the whole branch is "dead" code, which will never be executed; so if the code was there for a specific use case, it will not work correctly. I noticed this issue when porting the control to Uno Platform where I adjusted it to use the XamlRoot:

Looks like it closed mistakenly. Reopening.
