<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#12555
<!-- Either: -->
- [X] There are tests for these changes
There's still some small issues, but I suppose most of the work is done:
- test-tidy mentions a `method declared in webidl is missing a comment with a specification link` for the `getResult` method.
- I get an 'unused code' warning for code present in `UnionTypes.rs`, which is auto-generated.
Passing tests:
- [x] `FileAPI/reading-data-section/filereader_result.html`
- [x] `FileAPI/reading-data-section/filereader_readAsArrayBuffer.html`
- [x] `FileAPI/idlharness.html`
- [ ] `FileAPI/reading-data-section/FileReader-multiple-reads.html`
<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
