## Objective #61331

Ensure the Git panel receives focus when a file context menu is opened.
Previously, focusing the menu immediately could prevent the Git panel
from becoming focused.

## Solution

Defer focusing the context menu’s focus handle until the next window
update cycle. This allows the menu to be established before focus is
applied, preserving expected focus behavior in the Git panel.

## Testing

- Automated tests were not run.
- The change should be manually tested by opening a file context menu
from the Git panel and confirming the Git panel remains focused and
keyboard interaction with the menu works as expected.
- This is a UI focus change and should be verified on supported desktop
platforms.
