Can't long-click on Design A New Model

(Bug, Closed -> Fixed, Priority: Critical, Test Status: Functional tested , Reported By Bad Link: Thing 3y284of not found, )
UX, Mobile
Summary: My workflow involves having many different Querki tabs open at once. For the most part, this works easily. The Design A New Model button, however, does not respond to a long-click (which is the primary way of getting a new tab on mobile browsers).
It's not a problem with all buttons, as Write a New Page works fine.
