Query variables keep insisting that collection name is empty #51
Description
Hi!
Our database (around 1M) of entries contain MAC information about devices. We would like to have a variable to control what device statistics are being displayed on a plot.
Variables in dashboard are insisting that collection field is empty:
Pressing Enter, changing form focus does not help at all.
Grafana shows this error upon clicking the query button:

Collection form clearly is not empty.
