Description Jack Wiig 2023-05-31 14:17:46 PDT

Adding support for NSTextInputMarkedRangeAttribute gives macOS accessibility clients knowledge of where input method events are occurring.

Without this information, it's impossible for an assistive technology to know if the user is in an input-method composition context.
