[Search:WebCrawlers:ViewCrawler:Manage Domains page]Unclear announcement after activating Expand this extraction rule button

[L1nBra]

Description Change of button state should be clearly announced for user to understand what happened. Especially for the user using assistive technology.

Preconditions Stateful Web crawlers -> View Crawler -> Manage Domains page, Extraction rules tab is opened. Domain is added. Content field is added. Use Screen Reader (NVDA).

Steps to reproduce

1.Navigate to All actions button by pressing Tab key in the table. 2.Press Enter. 3.Navigate to Expand rule button by pressing Tab key. 4.Press Enter. 5.Observe the page and screen reader announcement.

NVDA Speech Viewer +UI elements

Actual Result

• Table appears, dialog for All actions closes, no announcement that button was expanded; strange announcement about "out of table clickable..."

Expected Result

• Announcement that button was expanded is made, and a)either focus should go to the table which appeared and table is announced or b) if focus should stay on All actions button - then no announcement about the table.
