Maximized Terminal window obscures Taskbar after monitor power save

### Windows Terminal version

1.20.11781.0

### Windows build number

10.0.19045.4651

### Other Software

Ubuntu in WSL2

### Steps to reproduce

I have a laptop with external monitor connected. The laptop screen is 1920x1080, horizontal, 125% scaling; external monitor is 3840x2160, horizontal, 150% scaling, extended. The external monitor is set as main screen. The Taskbar is visible on both screens and is blocked.

Steps to reproduce:
* Run Terminal, move to external monitor and maximize
* Open some other apps, move to external monitor and maximize (not sure this is required)
* Lock screen and let screens enter power save
* Unlock screen

The reproduction rate is 100% or very close to it.

### Expected Behavior

All applications including Terminal should appear normally, just like before locking screen.

### Actual Behavior

All other applications that I have appear normally, just like before locking screen.
Terminal obscures almost the whole Taskbar, just few bottom pixels are visible:

I need to Restore down and Maximize again to unobscure the Taskbar.

Start by reproducing the maximize, monitor power-save, and unlock sequence described in the issue on Windows Terminal 1.20.11781.0 with the stated mixed-DPI displays. Trace the terminal's window and maximize handling around display power-state restoration; done means the Taskbar remains unobscured after unlock without requiring Restore Down and Maximize again.
