ReloadConfiguration doesn't add a new [ssh] domain to existing windows #1279

What Operating System(s) are you seeing this problem on?

Windows

WezTerm version

20210814-124438-54e29167

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

No, and I'll explain why below

Describe the bug

When new ssh domain is added via the config file there is no way to see it in the Launcher (ShowLauncher) in existing windows even after explicit ReloadConfiguration. The only way to see it is to run another wezterm instance (from a powershell cmdline or via Windows start menu e.g.).

To Reproduce

1. Edit the config file and add an SSH domain
2. Run the ReloadConfiguration action
3. Open the Launcher (right-click on the + or run the ShowLauncher action) to see ssh domains. Check there is no domain you've just added.
4. Run new wezterm window via powershell or Windows menu.
5. Check Launcher in the newly opened wezterm window to see the ssh domain you've just added.

Configuration

no specific config

Expected Behavior

Launcher should pick-up the new [ssh] domain configured after the configuration reload.
