already checked options are updating when we search with server side render multiple options.

I am using the multiple options for mat-select and I am calling server side api on search in the input box.
when we select some of options and then search and select other options previous options are got deselecting.
Can any one help here with this.

Same here. Doesn't work well with multiple select. If you select "one" from "one", "two", search and select "two", your previous selection is erased.

Same here, the selection of the searched item deletes the previously selected items.
The only "search", without the selection, works fine; once you check the item, the already selected are erased.
