I am not sure that I understand, the phrases above sound contradictory.

In the 1st paragraph you say that it's install the one emitting the
phrase, in the second you say that keep and hold do emit, while others
(including install) do not.


Additionally, I tried to reproduce it and I cannot, I leave the
transcript below.


So if you have any idea that can help me to reproduce it, please tell;
otherwise I'll leave open to see if other people find the same problem
and can help.
