Switching OS input method resets Terminal colors and zoom

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

Windows 11
Version: 10.0.22000.258

Windows Terminal Preview
Version: 1.11.2731.0

### Other Software

Bash (in WSL)

### Steps to reproduce

1. Inside a `xterm` terminal, override the terminal's colors using escape sequences such as:

```sh
# Set "red" color to hex(ab4642)
printf '\033]4;%d;rgb:%s\033\\' 1 'ab/46/42';
# Set "background" color to hex(181818)
printf '\033]%d;rgb:%s\033\\' 11 '18/18/18';
```

The full theme I use can be applied using the following script https://github.com/fnune/base16-shell/blob/master/scripts/base16-default-dark.sh. This method allows me to conveniently switch between dark and light themes, regardless of the OS I'm currently using.

1. Assuming you have multiple input methods configured in Windows (e.g. I switch between "US" and "US-International" regularly), press either Ctrl+Shift or Win+Space to switch between input methods.

Switching input from the task bar using the mouse also triggers this bug.

### Expected Behavior

Switching input methods in Windows has no impact on the configuration of my open Terminal sessions.

### Actual Behavior

The terminal's colors get reset to the color scheme configured in Terminal for the current session.

Before switching input methods:

After switching input methods:

Reproduce on Windows 11 with Windows Terminal Preview, WSL Bash, xterm color escape sequences, and a Windows input-method switch. Start by tracing how input-method or window changes affect the active terminal session, especially its color and zoom state. Done means switching input methods preserves the session's customized colors and zoom.
