Search bar: Keyword time range time zone not set

[grotlue]

Expected Behavior

When setting the keyword time range for the first time the time zone should be set accordingly

Current Behavior

The first time updating the keyboard time range the /fields and /validate calls fail as the timezone is not set.
The second time it is set.

Request body:

{"timerange":{"type":"keyword","timezone":"","keyword":"Last five minutes"}}

In order to reproduce it, it is important to not change the keyword in the keyword tab in the timerange picker. What is interesting too, that there is no preview at this point.
