Multiselect search text stays/disapears in browsers

I have a multiselect field. Here there is a search field, when i search and click on an option the following is happening.

In chrome the text stays in the box. I search for “vi” click on video and in the search field the “vi” is there.
In safari the text disappears. I search for “bl”, click blog and the text disappears and i can search for the next option.

Not sure if this is a bug or an intended feature, but it is weird. Also hard to explain to the customer when we have different browsers.
