Tags not being differentiated in Interesting/Ignored box

edit

It looks like the Interesting/Ignored dialog boxed on the right-hand side no longer support adding multiple tags separated by space.

Entering "feature-request bug" and selecting the "add" button, I would expect to see 2 tags: feature-request and bug, but instead I see a single tag "feature-request bug"

Looks like the question's tag box behaves correctly.
