I don't understand this. tramp-connection-property-p just tests whether
a connection property is defined. It does not check the value of this property.

Sorry, but I'm not fluent with the cl-loop syntax.

Sorry, I cannot follow what you try to explain. Could you please show me
an example, both the value of tramp-cache-data, and the result
tramp-list-connections is returning?

At least it is unrelated to the problem of this bug report.
