Fixes: #893

Description of the change:

Take into account the current global target selection when updating probe table.

Motivation for the change:

See #893

Just a bit of hiccup here: #893 (comment)

But since switching target will eventually overwrite that incorrect intermediate state with correct information, we can leave it as it is?

Makes sense. There are probably similar examples like this elsewhere, too. I'll test this out soon to make sure it works as expected.
