Yes, I can reproduce it in Private window in FF with all add-ons disabled. And on 46.0.1 also.
But it affects only cluster's name. When I try to rename cluster on Dashboard, typing of "_" erases all the text. On Settings and Network tabs it works.
By the way, in Google Chrome it is not reproducible.
