What to change
Ask your supplier to keep interaction within an active popup until it is dismissed, while making the intended closing behaviour clear.
A worked example
Illustrative example
While choosing contact preferences in a popup, the visitor cannot accidentally follow a dimmed service link underneath it. Closing restores the normal page.
Why this matters to your practice
When a popup temporarily becomes the active task, the dimmed page behind it should not remain unexpectedly usable. Otherwise, a person moving by keyboard may follow an unseen link while trying to complete the panel. Ask your supplier to demonstrate movement forwards and backwards through its controls, along with background tapping on a phone. Decide whether tapping outside should close the panel separately. The key is that the visual impression and the actual available actions agree.
A practical review example
A dimmed service link behind a preference panel should not suddenly open when someone moves through the popup by keyboard. Ask your supplier to navigate forwards and backwards through all its controls, then try the background on a phone. The visible impression of an active separate task should match the actions actually available. If tapping outside is meant to close it, verify that decision separately and confirm it does not also activate an obscured link or discard meaningful work without the agreed explanation.
How to check the result
Accept when background content is appropriately inactive during the popup task and becomes fully usable again when the popup closes.
A mistake to avoid
A dark translucent backdrop changes appearance but does not by itself prevent background controls from receiving focus or activation.
