Description

When the list of contacts, tasks, or other entities changes, deselect any that were removed from the list.

Testing

• Go to the tasks page and select 2 tasks. You should see "2 Selected" in the header.
• Change the tasks filters so that only one of the selected tasks is visible. You should see "1 Selected" in the header.

The code and UI look great! On the first test, it removed all of my selected tasks, but on the second test it worked as described. - It also did this on contacts.

On the first test, it removed all of my selected tasks.

@dr-bizz Good catch! That should be fixed now, as well as a performance improvement. Instead of waiting for the contacts or tasks to load before loading the mass selection ids, we load the mass selection ids immediately.

This works well in the UI, and the code looks great. I didn't know you could fetch previousData. At first I was worried that if no tasks are present, it would default back to the previousData, but that isn't the case.
