Possible bug in 4.23.2 when self-hosting assets / react

[melgish]

It looks like the 4.23 release of arcgis/core changed something that broke release builds using react. 
I created a repo that demonstrates the error here https://github.com/melgish/map-issue

The map renders fine while in development mode, but when built for release, the map frame renders, but it never pulls any tiles.

If I downgrade to 4.22.2 and rebuild, everything works as expected.

Not specific to local assets, but you need to update the browserlist for your production build in the package.json

I'm surprised it worked in 4.22, but some of the down-compiling and babel helpers with the default browserlist will break some stuff. There's no errors, which is odd, but updating for evergreen browsers fixes this issue with CRA.
