Bug: Quake mode (globalSummon) animation with dropdownDuration=0

### Windows Terminal version (or Windows build number)

1.10.2383.0

### Other Software

Windows 1909 (build 18363), might be relevant for repro since it's about the actual window.

### Steps to reproduce

Add the following action to `settings.json` under `"actions"`:
```json
{ "keys": "win+`", "command": { "action": "globalSummon", "name": "_quake", "dropdownDuration": 0 } },
```
First press Win+` to launch the quake window.

Then press it again to hide, and another time to show the quake window, and notice the show/hide animations.

### Expected Behavior

Both the hide and show animations should be instant, no animation should play and the window should appear and disappear instantly.

### Actual Behavior

The hide animation works as expected, but the show animation is no longer a reveal from above but rather a zoom out and pan (to top left) for some reason.

Changing `"dropdownDuration"` to 1 instead of 0 works as expected, a workaround.

If it doesn't repro for you, perhaps the Windows version is important.

Trace the globalSummon action and dropdownDuration handling from the settings.json action shown, then follow the window show/hide animation path. Reproduce with dropdownDuration set to 0 and verify that both transitions are instant, including reopening the quake window.
