AnalyticalTable: infinite scrolling with small chunk size does not allow to see all the data

[cmealares]

Describe the bug

When infinite scrolling uses a small chunk size, the table does not display the scrollbar.
Thus, the user cannot scroll down and can never see all the data.

Isolated Example

https://codesandbox.io/s/interesting-kepler-r3gy8y?file=/src/App.js

Reproduction steps

1. Scroll down to get the next chunks of data. You can't because there is no scrollbar.

If you modify the code to use a bigger chunksize (say 50), then the scrollbar is visible again.

Expected Behaviour

The user must be able to access all the data.

Suggestion:
Force the scrollbar to be visible when infiniteScroll is true. And trigger onLoadMore() when the user tries to scroll down.

Additional Context

Organization: SAP

Independently of the chunk size, This issue can also happen with property isTreeTable= true:

• Load a big chunk of data that is all under the same root
• When this root node is expanded, the user can scroll down and see the rest of the data
• But if the user collapses the first table node, then the scrollbar disappears and he cannot access the rest of the data.

Hi @cmealares

unfortunately we have to reject this feature request for the following reasons:

• As far as I know, no Sap/OpenUI5 table supports this option either
• The implementation would feel weird, we would either have to add empty rows at the bottom of the table, which would then look strange when updating, or increase the height of the table body to make it scrollable, which would look weird when scrolling.

In my opinion, it would be better to use a "load more" button below the table in this case.
