### Type Fixes & Improvements

Various improvements were made to the types. Potentially the most impactful of which is that the `target` and `ancestry` property now return as `UnlabelledFrameSelector` instead of as `string[]`, which is incorrect for selectors involving shadow DOM. This may create some issues during migration for any code that has been incorrectly assuming these two properties have the `string[]` type. For more details and other type changes, see the commit itself:
