@Volen99 found that the fix for #2119 and #2124 is the reason why items are cut off. This PR reverts this fix, but this leads to #2119 again.

Summary of our investigation:

1. igCombo - Duplicate items are displayed if dataSource contains both half-width and full-width characters and virtualization is enabled. #2124 is reproducible in 20.1, but is not reproducible in 22.1, even without the "fix", so let's ignore this issue for now.
2. Don't remove the fix for igCombo - visibleItemsCount does not work properly if dataSource contains both half-width and full-width characters. #2119 . Instead, set height using custom css. See if visibleItemsCount works properly. If not, investigate if setting the height is the reason for this, or something else in the code.
3. If setting a height breaks the visibleItemsCount, then just removes this fix, and will suggest a custom work around for igCombo - visibleItemsCount does not work properly if dataSource contains both half-width and full-width characters. #2119
4. In the end, retest all bugs - Combo is not showing items visually correct #2174, igCombo - visibleItemsCount does not work properly if dataSource contains both half-width and full-width characters. #2119 and igCombo - Duplicate items are displayed if dataSource contains both half-width and full-width characters and virtualization is enabled. #2124
