## Description
**Problem**
When deleting a List widget in the EE environment, the widget is
successfully removed, but errors are displayed in the in-app debugger.
These errors disappear upon refreshing the page, leaving users confused
as to why the errors appeared in the first place, despite the widget
being deleted correctly.
**Root Cause**
- The issue arises from the sequence in which widgets and their
associated meta widgets are deleted.
- When deleting a widget with meta widgets (e.g., a List widget):
- The main widget is removed first via the deleteWidget saga.
- Meta widgets are then deleted later during the componentWillUnmount
lifecycle method.
- The lint evaluation runs between these two processes, detecting meta
widgets still present in the state without a parent widget.
- This mismatch triggers errors in the in-app debugger, which disappear
once the page is refreshed, as the meta widgets have already been
deleted by then.
**Solution**
- We have modified the deletion process to ensure that both the main
widget and its associated meta widgets are removed within the same
action.
- Instead of handling meta widget deletion in the general deleteSaga:
- We now check for widgets with the hasMetaWidgets flag within the
deleteWidget saga.
- If such widgets are found, their meta widgets are deleted before the
main widget is removed from the layout.
- This adjustment ensures that the lint evaluation occurs after both the
main widget and its meta widgets have been removed, preventing errors in
the debugger.
