A script overlay hides problems that remain in the source

Checks

• Accessibility overlay detected overlay_detected
• Failures appear only without overlay failures_only_without_overlay
• Overlay introduces new failures overlay_introduces_new_failures
• Overlay widget itself not accessible overlay_widget_itself_not_accessible

Findings

• An accessibility overlay changes what the scanners find
• The overlay's own widget has accessibility failures

What this relies on

The source must conform on its own; an overlay is temporary.

How to verify by hand

A screen reader user; overlays often fail them.
