Crash when quitting presented NavigationView in sidebar or panel

[dgelessus]

Whenever I present a ui.NavigationView as sidebar or panel and try to quit it using the built-in X, the app crashes. I've tried implementing a custom quit button using View.close(), but that doesn't seem to do anything. View.close() works just fine with other presentation modes like sheet or popover.

A workaround to this is to create a View, set the NavigationView as its subview and then present the regular View. Although it fixes the crash when quitting, it causes a few layout problems due to the NavigationView not being the presented view.

@omz, if necessary I can provide crash reports, if that would be any help.

This still seems to be a problem.
