Cannot type in new pane or tab until focus is manually activated with mouse click

### Windows Terminal version

1.14.1451.0

### Windows build number

10.0.19042.0

### Other Software

_No response_

### Steps to reproduce

Create new pane/new tab

### Expected Behavior

It is possible to type in the newly opened terminal

### Actual Behavior

Unable to type until I click on the new terminal.

Note that enabling the option "Automatically focus pane on mouse hover" partially prevents the issue from happening.

It seems like focus is removed from all terminal tabs/panes whenever a new one is created.

Reproduce the issue by creating a new pane or tab on Windows Terminal 1.14.1451.0 and verify whether keyboard input is accepted without a mouse click. No source files or tests are identified in the issue; done means newly opened panes and tabs automatically accept typing while preserving the existing focus behavior.
