✨ macOS Accessibility `kAXLineForIndexParameterizedAttribute` not obtainable through the AX APIs

[godbout]

Description

it should be possible to get the current line number through the AX APIs by giving a location in the TextArea. currently it doesn't work and the API returns parameterizedAttributeUnsupported. might be linked to macOS Accessibility data missing in CodeEdit. (see #114)

this makes it impossible to apply Vim motions in CodeEdit through the AX APIs. a real pity!

Alternatives Considered

at that point i can't find any alternatives, because getting the right line number is a crucial part for navigating through the TextArea with the AX APIs.

Additional Context

calling AXUIElementCopyParameterizedAttributeValue(axFocusedElement, kAXLineForIndexParameterizedAttribute as CFString, location as CFTypeRef, &currentLine) returns parameterizedAttributeUnsupported rather than filling the currentLine with... the current line number. location is a character location in the TextArea (0 for beginning of document).
