Comment 4 for bug 1836813

Ah I think I understand what you are saying, if you have a search for
XYZ and edit XYZ to make it ABC and then press Enter twice XYZ
disappears from the list, because he search is re-applied. Note that the
edit you made is not lost, simply hidden, clear the search and you will
see it again. The simplest solution is to just have the tag list retain
keyboard focus after editing completes and to have the search also
search the was column for the original name.
