Code Review
This pull request fixes a crash that occurs when a Preview annotation is used with non-constant parameters. The fix involves checking if computeConstantValue() returns null and, if so, ignoring the invalid preview instead of crashing. The changes are applied to both single Preview annotations and MultiPreview annotations. Additionally, new tests are added to verify this behavior, and existing test code is refactored for better maintainability by using a mixin. My feedback includes a suggestion to improve code clarity and robustness in one of the changed utility functions.
