[AnalyticalTable]: [a11y. Screen readers don't read whole information]

[Kalita-Roman]

Describe the bug

When the AnalyticalTable enters any pop-in mode and some cell content is moved into the first column, not all the content is read by screen readers.

Violation of:
WCAG 2.1, 4.1.2, Level A, Name, Role, Value
EN 301 549 V3.2.1 (2021-03) 9.4.1.2, 10.4.1.2, and 11.4.1.2

Isolated Example

https://sap.github.io/ui5-webcomponents-react/v2/iframe.html?globals=&args=&id=data-display-analyticaltable--responsive-columns&viewMode=story

Reproduction steps

1. Open an AnalyticalTable with any popinDisplay mode, e.g. https://sap.github.io/ui5-webcomponents-react/v2/iframe.html?globals=&args=&id=data-display-analyticaltable--responsive-columns&viewMode=story
2. Shrink the viewport to achieve a pop-in effect.
3. Run a screen reader (NVDA or JAWS)
4. Try to read out all info in the cells

Current behaviour:

JAWS reads:

Current width: auto
grid with 4 columns and 8 of 500 rows
Name column header
column 1 row 1
Name Allen Best Contains Controls
Row 2
Name Combs Fleming Contains Controls
Row 3

Expected Behaviour

On accessing a data cell in the ‘Name’ (1st) column, the screen reader must announce all the content within the cell, along with any necessary additional information, without omitting anything.
