Actual Result

• [step 2, 4] Role mappings table has 6 rows present, but is announced as "table with 7 rows... This table contains 6 rows out of 6 rows". Users table has 1 row present, but is announced as "table with with 2 rows... This table contains 1 rows out of 1 rows".
  [step 7] No announcement about no results found. Tables are announced as "table with 2 rows... This table contains 0 rows" (for both tables).

Expected Result

• [step 2, 4] Tables are announced correctly. Role mappings table that has 6 rows, Users table that has 1 row.
  [step 7] Announcement about no results found is made when search doesn't provide anything. Tables are correctly announced, that they have 1 row without any data (or only announcement about no results found is made).
