[Interop] Fix coalesced/predicted event targets in trusted events.
Our past attempt [1] to fix the targets in untrusted events
accidentally reset the targets in trusted events! This CL fixes the
bug and updates the WPTs.
The change is still in "experimental" state. We will flip it to
"stable" in a separate CL.
