Subject: [PATCH] [terminal] IJPL-215631 Fix reporting zero typings in terminal
 popup completion

`LookupUsageTracker.MyLookupTracker.MyTypingTracker` is listening `beforeAppend` event that doesn't arrive because our custom prefix updating logic doesn't call `fireBeforeAppendPrefix`.


(cherry picked from commit a3b311995f70a5f59e9da24f34323bd08ce05c58)
