Changing basemaps after loading a user web map on UWP causes map display to behave erratically

[mikewilburn]

I've only been able to reproduce this on UWP so far.

Steps:

1. Sign in to the app
2. Load one of the user's web maps
3. Zoom to a location where data for that web map appears
4. Select a new basemap to display

Based on some testing, it appears step 3 is essential to getting the odd behavior. If I preserve the map extent to an area where the web map does not show data/layers, changing basemaps seems to work fine.

Update: closing and re-opening the app appears to be the only way to resolve this issue and start fresh.

@mikewilburn I am not able to replicate this. Can you retest please

This seems to an issue specific to the UWP app when running it on Parallels on a Mac. I sat with Mara for a bit of time and we weren't able to replicate on her identical UWP app which runs on natively on her Windows computer.
