LIGHTROOM CC - Keyword Suggestions doesn't remove deleted Keywords immediately like Keyword Set does.

When a keyword is deleted from the Keyword List, Keyword Set is updated immediately, but Keyword Suggestions is not.

It would be really helpful if Keyword Suggestions was updated immediately when the Keyword List is modified, especially to respect deletions of keywords no longer used.

This is occurring in Adobe Photoshop Lightroom CC (2015.1 Release).
