In a combobox one can type text which leads to the suggestion list to be filtered to only show values matching the typed string.
When now clicking the Select-All-Option not only the shown filtered values will be selected but all values without respect to the typed filter.
In the Sample “Forestry” does not contain the character “i” but is getting selected as well, although the combobox is filtered on “i”.
Expected behavior: Using the Select all checkbox on a filtered list only checks filtered list elements
Actual behavior: Using the Select all checkbox selects all on a filtered list selects all list elements
