September 10 2019 Update breaks CQUI

**Describe the bug**
Steam pushed the 1.0.0.341 (443561) update and it appears to have broken at least the use of spies. Can't select a mission or move cities. The border of the button turns yellow when I select them but the menu never pops up.

**To Reproduce**
Steps to reproduce the behavior:
1. Select a spy
2. Click on either "Choose Mission" or "Travel to New City"
3. Menu is not displayed for either option.

**Expected behavior**
Should see the menu appear to give me either a list of missions or which city to move to.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**General informations**
- OS: Windows 10
- Version 1.0.0.341 (443561)
- Expansion Rise and Fall

Reproduce the issue in Civilization VI with CQUI using Windows 10, Rise and Fall, and version 1.0.0.341 (443561), following the spy mission and travel steps. Trace the UI path for both buttons and confirm that the mission and city-selection menus appear after the fix.
