Misleading message in deletion confirmation modal with "select all x elements"

Steps to reproduce

1. Visit any page with a tracks list (like at /content/libraries/tracks/) with more than 25 tracks
2. Select all displayed tracks with the table header checkbox to reveal "select all x elements" link (I agree with #447 (closed) btw)
3. Select all tracks with "select all x elements"
4. Execute "delete" action to reveal confirmation modal

What happens?

Modal message warn about the deletion of the number of selected and displayed tracks.

What is expected?

Modal message warn about the deletion of the number of selected tracks or something generic like "all elements".
