Type: Bug Report
Angular Dropdownlist: Grouping information disappears if the item at the top of the popup is disabled.

1.) Use grouping functionality for the drop list's data.

2.) Have at least one item disabled. (Easiest to replicate if the first item is disabled)

3.) Click on dropdown to open the popup.

4.) If first item is disabled notice the group it belongs to is not displayed in the popup. If the first item isn't disabled scroll until disabled item is at the top of the list and the group information will be cleared.


Easily replicated if you modify the stackblitz from this page to disable the first item in the list



"Meat" should be displayed in that empty row at the top. Lines 12 and 26-28 are the only modifications made to the code found at the url above.
