fdp-table with grouping performs very slow

[tomsawdayee]

Describe the bug
I'm using "@fundamental-ngx/platform": "0.33.5"
I'm trying to use the fdp-table component with grouping feature as described here, in an Angular application -

https://sap.github.io/fundamental-ngx/#/platform/table#groupable
When grouping by a certain column, the performance is very bad and takes too much time.
See in the example page, there's generated violation in chrome's console, and this is with a very small amount of items.
When running this example with a dataset of ~200 entries, each group takes a few seconds. Even the collapse\expand action is very slow.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://sap.github.io/fundamental-ngx/#/platform/table#groupable
2. Click on 'Group' button to group by an element, then expand\collapse a grouped item
3. See violation issues in chrome debugger

Expected behavior
Performance of grouping should be better
