# Regression test: Recursive animation callbacks
|
|
# Issue: Animation callbacks that started new animations caused segfault in AnimationManager::update
|
|
# Fixed by: Deferring animation removal during update loop iteration
|
|
#
|
|
# This test verifies that:
|
|
# 1. Animation callbacks can start new animations on the same property (REPLACE mode)
|
|
# 2. No segfault occurs from iterator invalidation
|
|
# 3. The animation chain completes properly
