Can't click-to-collapse the tag picker modal

[susodapop]

Issue Summary

The tag picker is hard to close. It's impossible to tab to the OK button after picking tags with mouse or keyboard. Pressing Esc drops the selected tags. And clicking the <select> box itself has no effect. Only by clicking some white space in the modal can you reveal the OK and Cancel buttons.

Steps to Reproduce

1. Open the tag modal
2. Add some tags
3. Observe that the OK and Cancel buttons are hidden by the dropdown with no obvious way to collapse it.

Clicking the <select> tag elsewhere in the app will collapse its drop down. But the behavior isn't consistently available. On the visualization editor the X-axis field picker can click-to-collapse but the Y-axis field picker can't, for example.

How to fix

Make the tag picker collapse/expand when clicked. Or change the tag picker so its OK and Cancel buttons are always visible. Here's how Intercom does it.
