This patch fixes a bug in the feature loader where a
RuntimeError: dictionary changed size during iterationcould occur iffeature_toggleswas mutated while iterating over its keys.The fix wraps the iteration in
list(...)to safely snapshot the keys before the loop begins, preventing any potential crash.This PR is based on a new v5 branch created from the v5.12.3 tag to support patch releases for the 5.x line.
