Describe the bug

We are trying to implement a feature where a user may act on possibly hundreds of rows of data which is dynamically loaded into an AnalyticalTable using a scroll-triggered infinite load. Our issue is that upon scrolling down, the newly loaded rows are not selected, and the selected all checkmark switches into the indeterminate "some rows selected" state.

This forces users to press select all after every single data load until the desired amount of rows are selected, which is very counter-intuitive and could easily result in users not noticing that less data is selected than intended.

Isolated Example

No response

Reproduction steps

1. Create an AnalyticalTable with a scroll-triggered infinite load andselectionMode set to multiple
2. Enable select all by checking the mark on the top left corner.
3. Scroll until new data is loaded
4. Observe that the new data is not selected and the checkmark has turned into a square.

This page is kind-of an example, however, for some reason it completely deselects everything on more data load: https://sap.github.io/ui5-webcomponents-react/v2/?path=/story/data-display-analyticaltable--infinite-scrolling&args=selectionMode:Multiple

Expected Behaviour

If select-all is enabled: All newly loaded rows should be selected as well.
If only some rows are selected: The selected rows' state is preserved.
