Unable to create a new session from specific branch

### Short summary

Unable to create a new session from a specific branch for project from WSL host

### Affected version or release

1.1.14

### Installation context

_No response_

### What happened?

I'm unable to create a new session from a specific branch for a project from the WSL host. Clicking on the "Create from ..." button does nothing.

However, if the project is on Windows, clicking on the "Create from..." opens a dialog prompting to select a branch.

### Steps to reproduce

1. Enable "WSL host (Preview)" feature
2. Restart GitHub Copilot App
3. From **Environments** in **Settings** , add the "Ubuntu (default)" host
4. From the "WSL: Ubuntu" remote host, add a project on the WSL host
5. Exit **Settings**
6. Locate the recently added project in the list of projects
7. Hover over the project and click the "Create from..." branch icon
8. Observe that nothing happens

### Expected behavior

Clicking on the "Create from.." branch icon for a WSL host project should open the branch selection dialog the same as doing so for a Windows host project works.

### Additional context

Screen recording attached.
