Description

Currently onFilterControls (in the filter control extension) is called when the DOM elements for filters are created. However, for select elements, this is done before option elements are added. This means that the event cannot be used for any operation that requires the value (or options) to be retrieved or updated. It would be great to have an event that is called when the filter control values are populated (or updated).

Related: #6030 (comment). Note that use of onSearch, since onFilterControls would not work for selects since options are not set at that point.
