…bled Remove list options from the tab order when the entire slection list is disabled. Fix accessibility issue where end user can tab to a disabled selection list. ``` <mat-selection-list disabled> <mat-list-option>A</mat-list-option> <!-- ^ should have tabindex="-1" since entire list is disabled --> </mat-selection-list> ``` Approach is to consider a disabled mat-selection-list with a mat-list-option having `tabindex="0"` an invalid state. When disabled Input on the seleciton list is set to true, set tabindex to -1 on every list option. fixes angular#25730
