Frames with focusable content must not have tabindex=-1
What is the problem?
The frame-focusable-content rule ensures that frame and iframe elements that contain focusable content do not have a tabindex of -1.
Impacted Groups
Why is this important?
When a tabindex of -1 is applied to a frame or iframe, it prevents keyboard users from navigating to and interacting with the content within that frame. This can exclude users who rely on keyboards for navigation, such as those with motor impairments.
How to solve this issue
To fix this, either remove the tabindex attribute or set it to a positive value. This will allow keyboard users to access the content within the frame and interact with it as intended.
