Bug Report

When writing annotation query using google bigquery datasource, the tooltip of the annotation is not showing and an error is thrown in the console:

Here's the error:

angular.js:14800 TypeError: l.replace is not a function

    at Object.invoke (angular.js:5106) "<annotation-tooltip event="event" on-edit="onEdit()">"

Here's my annotation query:

SELECT `created_timestamp` AS time, CAST (`platform`AS String ) AS tags,
`id`, `versions_count` as text FROM `midyear-choir-151316.Test.ts`
WHERE `created_timestamp` BETWEEN TIMESTAMP_MILLIS ($__from) AND TIMESTAMP_MILLIS ($__to)
ORDER BY 1,2 LIMIT 1280

Expected Behavior

The annotation tooltip should be showing

Actual Behavior

The annotation stays hidden and there is an error in the console

1. Create an annotation query using bigquery
2. hover the annotation to display the tooltip
3. Notice that the tooltip stays hidden.
