Interestingly enough, and upgrade to version 5.0 (beta for Linux)
appeared in the Google RPM repository recently (I just noticed it this
morning). Unfortunately, this particular bug remains.

Here's a seemingly 100% repeatable way to reproduce this bug:
Enter "List" then move the cursor to the beginning of the field and
enter an extraneous letter (one that never appears before "List" in an
actual class name); all the entries will be removed, as they should.
Now backspace to delete that extraneous letter. Some entries
with "List" in their name will reappear, but many will be missing. Now
just arrow-key to the right (clicking with the mouse won't do it) and
the missing entries will appear.

This phenomenon can be seen in other cases, but often you perceive
something to have altered in the list, but it's to small a change to
look like more than a flicker on the display. With the List example,
the change is large and blatant.

Incidentally, they've achieved some serious performance improvement in
their JavaScript interpreter with version 5.0, 'cause now filtering is
much faster. Very bearable.
