Pane history not being saved (GitBash)

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

Windows 10 , Version 21H1 (OS Build 19043.1288)
Windows Terminal Preview Version: 1.12.2931.0

### Other Software

Git 2.33.1

### Steps to reproduce

I have three Git Bash panes in my Windows Terminal Preview setup.

I close Windows Terminal Preview by clicking the `X` button in top right of application.

When I re-open, my most recent history is not accessible in any of these three panes (ie pressing the up and down arrows on the command line).

It seems to have saved history from before I installed Windows Terminal Preview.

I have a `.bash_history` file in `C:\Users\Me` and I can see the history entries in that file.

I don't seem to have a `.bash_profile` file in that location (as related answers on stack overflow have suggested looking at).

### Expected Behavior
