From @accesswatch:

• Remove redundant role=textbox and static ARIA attributes from QuickInputBox
• Dynamically set aria-haspopup and aria-autocomplete only when list is active
• Track state to avoid unnecessary attribute changes that cause re-announcements
• Add picker.ariaLabel and item ariaLabel for Go to Line dialog
• Improve post-navigation status announcement with line/column info
  This allows screen reader users to:
• Type and edit text normally with arrow key navigation
• Hear characters as they type in the input field
• Get proper announcements when navigating list items
  Fixes screen reader accessibility in Ctrl+G Go to Line dialog.
