I misunderstood the steps and the description of the anticipated issue
you listed.

The last step you said:

    M-x ad-deactivate TAB

I believe it should be instead:

    M-x ad-deactivate RET TAB

That is, you expect that the completion framework lists "open-line", but
instead it shows an error.

In this case, I can reproduce this issue in both my 29 and my 28.1
build, and I have attached the build information for these two builds in
my previous reply.

Best,
