Dropdown List opening to top with position bug

[6amalgama9]

I used angular2-multiselect-dropdown v.5.0.4 and angular v.12.

While testing I figure out that position bug of dropDown list is only depends on this 3 settings in different combinations:

• enableSearchFilter
• enableCheckAll
• enableFilterSelectAll

I think the height of elements which appear by depending of those setting is missed on calculating the top position of the list (when the list is openning to the top). And some events such as 'Select All' also miss firering of recalculation of list position (below will be screenshot).

For example, single and multiple select without any turned on options from above:

DropDown List apears in propper way only if enableSearchFilter and enableCheckAll setted to 'true'.

But even in whis case , when you click on 'Select All' checkbox or try to search, position of dropDown list is move out.

Position "to bottom" is always a properly.

Here is my Stackblitz example.
