Close UI right after ask execution of an Alias

[jibedoubleve]

Description

When using the @multi@ macro in our application, the UI becomes unresponsive. It appears that the UI waits for all processes initiated by the @multi@ macro to complete before allowing any further interaction. This causes significant delays and a poor user experience, as the UI remains frozen until all processes are done.
Steps to Reproduce

1. Trigger the @multi@ macro in the application.
2. Observe the UI behavior during the execution of the processes initiated by the macro.

Expected Behavior

The UI should remain responsive while the @multi@ macro processes run in the background. Users should be able to interact with other parts of the UI without having to wait for all the processes to complete.

Analysis

Update may occur in MultiMacro.ExecuteAsync
