* fix types

* switch to using table panel in e2e test

* use regex for partial text match

* actually go to the dashboard...

* use include.text

* check for visibility first

* try waiting on backend request to complete

* CI driven development is fun

* make sure we're waiting for both data query calls

* open dashboard instead

* kick drone

* Revert "open dashboard instead"

This reverts commit bab9c77c4d.

* check timezone second

* refactor to avoid detached elements
