Fix django_form events sometimes not occurring #272
Description
Current Situation
Sometimes django_form events such as on_error will not be executed.
This appears to be caused by a race condition where the use_effect(render_form) hook could be cancelled prior to full execution.
It is presumed that this issue is related to current ReactPy use_effect design that cancels all async effects upon every re-render. The set_state function queues a render, and fact that set_state is asynchronously being called in several locations within the django_form component is likely causing abrupt re-renders (which subsequently causes early use_effect termination).
Proposed Actions
This issue will likely need to be resolved in ReactPy core, and might require creating an effect rendering queue on a per-component basis.
