Original Pull Request: https://github.com/microsoft/terminal/pull/14630

State: closed
Merged: Yes

Directly manipulating the NavigationView::MenuItems vector is bad. If you do that, you're gonna get crashes, in WinUI code for Measure. However, a WinUI PR (below) gave me an idea: Changing NavigationView::MenuItemsSource will wholly invalidate the entirety of the nav view items, and that will avoid the crash.

This code does that. It's a wee bit janky, but it works.

Closes #13673

might affect #12333, need to try and repro.
