Unable to set Select All check box to checked state when all options in list are selected

[NareshKumarM]

Hi Naresh,

I have a mat-select-autocomplete control in one of my app's filters.
It works well with the functionality expected for the filter.
When I reset the filter, i am setting all the options in the list as selected but the Select-All check box next to the search control is does not appear to be checked.

Is there a method to set select-all too checked upon resetting the filter?
