ListViewFilter - Variable unselect while searching

[PrimozGodec]

What's wrong?

Widgets that use ListViewFilter "forget" selected variables filtered out while searched. Watch the video below. In the console, I print selections. When a variable is filtered out by searching, it also gets removed from the setting, and a commit is called.

For example, when Petal length and width variables are selected, they get unselected when they are filtered out from the view.

I would expect the variable would still be selected as it was in the deprecated ListViewSearch

How can we reproduce the problem?

Use a unique widget. Select petal length and width. Start typing "sepal" and then remove the filter. Previously selected variables are no longer selected.
