Snapshot Obsolete Warnings with '.only', '.skip' or '-g' Flag

[cdxOo]

When using matchSnapshot() in conjunction with 'test.only()', 'test.skip()' or the '-g' Flag I receive a warning about the snapshots from the omitted tests being obsolete (i.e. "1 snapshot obsolete from 1 test suite. To rem....").

In addition this message does not just appear multiple times at once like this:

I am not sure if this is a bug or I am missing something here.
