Yes, but it is not what I reported initially [1]; it was:

However, I am not able to reproduce; because I removed this profile – it
comes from my attempt to reproduce Docker pack.  Other said, note that

Trying other examples, I am not able to see it again.  Hum?!


Sorry for the noise if it is a bug between the keyboard and the chair. ;-)

Sorry for the noise.  The current behaviour is the one we agree and is

Well, time for me to take summer holidays? :-)
