When using the "Add New Tag" functionality (Alt-Shift-A), the list of "matched" tags includes the portion of the tag name typed so far, even though it is not a known tag name.

This results in requiring an extra keystroke to skip past the partially typed name of the tag when trying to select one from the list of known tag names.

As an example, if I type "ge" in to the tag name field, that is enough that it should narrow the list to a single entry, which is "genre".  Except that the "ge" is in the list as well. 

This problem did not exist in the prior version of picard (2.5.6) I had been using until recently.
