[ic-data-table] - issue with row heights when data sorted

### Summary of the bug
When using a datatable with globalRowHeights and truncation, the row heights change when sorting the table

### 🪜 How to reproduce
Tell us the steps to reproduce the problem:
1. Go to page: https://stackblitz.com/edit/nn9bpjgz-gab6qusc?file=src%2Fapp.jsx,package.json&hideExplorer=1
2. See that all rows are the same height (the configured globalRowheight):

3. click the sort button in the Name column
4. See the error - the rowheights are now uneven:

5. click the sort button again and see that row2 (which previously had a long truncated description), is now still honouring the full globalRowHeight value

### 🧐 Expected behaviour
I am unsure what the actual behaviour should be. I believe the intention is that all rows should be the globalRowHeight as they are when first loaded. Although there is maybe a case to only make the rows fill the space they require eg 1 line & then have the globalRowHeight as a maximum

### 🚨 Urgency (low, medium or high)
Low - at present we can hide this by disabling sorting

Reproduce the issue in the linked StackBlitz example using ic-data-table with globalRowHeights, truncation, and sorting. Start by tracing the table's row-height handling during sort and clarify whether rows should remain uniformly sized or shrink to their content. Done means the chosen behavior remains consistent after repeated sorting.
