fix: take into account static blocks when determining transition locality

[dummdidumm]

The "is this a transparent effect we can ignore" logic for determining whether or not to play a local transition didn't account for pruned block effects. This fix marks the child branch as transparent if the block effect was, and during traversal then checks if the branch is the child of a block - if not that means it's the child of a pruned block effect.

fixes #16826
