[Security:Cases:View page]Incorrect announcements for Alert table elements

[L1nBra]

Description
Elements should be announced clearly without too much additional information for the users using assistive technology.

Preconditions
Security -> Cases -> View page.
Use Screen Reader (NVDA).

Steps to reproduce

1.Navigate to Alerts tab.
2.Navigate to first table element.
3.While pressing arrow keys, navigate through table element.
4.OBserve screen reader.

UI elements + NVDA Speech Viewer

Actual Result

• Screen reader is announcing all values, elements present in the table when user reaches Actions column values for the first line (there buttons present: View details, Investigate in timeline...). When user navigates to View details button separately, screen reader announces "View details...button", but button only after announcing all values in other columns for the first line.

Expected Result

• User hears only correct elements. And would be enough for user to mention that it is f.e.: for row one instead of announcing all values in the row when navigating to each element separately. Otherwise user can easily miss on what element he/she is at the moment, or even get lost in the page.
