AX: insertionPointLineNumber hits the main thread even for single-line text
fields
https://bugs.webkit.org/show_bug.cgi?id=265952
rdar://problem/119264904
Reviewed by Andres Gonzalez.
When a text field can only be single-line, either because it's an INPUT element
or because
aria-multiline=false, we shouldn't hit the main thread for
insertionPointLineNumber - just
return 0.
This can make navigating through web forms more responsive even when the main
thread is
blocked.
