Reproduce the issue in Chronograf 1.10.1 by typing ':' in the query builder for `owner = :owner:`; the report says pasting the same text works. Start from the query-builder UI and trace the reported `getInstance` failure in the bundled `index.c5ba09e6.js`; done means typing the colon no longer throws and the template-variable query remains usable.
