描述

Environment

  • Package version(s): 5.8.2
  • Browser and OS versions: Edge, Chrome, MacOS Sonoma 14.4

Feature request

When a Dialog or Drawer is open, the background elements should be un-focusable and hidden. This is backed up by this source and this source. Otherwise, the screenreader cursor could focus on something behind the Dialog/Drawer.

Examples

Currently when navigating by headings (CTRL+OPT+U on Mac) using a screenreader, currently when a Dialog or Drawer is open, the headers in the content underneath the overlay are also included in header navigation, which is unexpected.

研究方向
Investigate the Dialog and Drawer components in the Blueprint source code (likely under packages/core/src/components/dialog/ and drawer/). Determine how to apply `aria hidden="true"` to the root container or sibling elements when a dialog is open, and ensure focus trapping is implemented correctly. Refer to the WAI ARIA pattern for modal dialogs linked in the issue. No linked PRs or comments are available yet.
