Environment

Windows build number: Microsoft Windows [version 10.0.18363.815]
Windows Terminal version (if applicable): 0.11.1191.0

Any other software?

Steps to reproduce

Just open the terminal

Expected behavior

The window should have an acrylic background. I already set "useAcrylic": true in settings.json, as shown below:

// To view the default settings, hold "alt" while clicking on the "Settings" button.
