feat(filters): Fill operator part if only one operator exists
This MR introduces auto-filling the first operator part of the token if only one operator exists.
In order to make this work properly, two fixes was made to codebase:
- fixed wrong data source for "title" dropdown
- switched from
click
tomousedown.native.prevent
as source for "click" for items - having "click" causes multiple issues in Safari due do different timings of blur/DOM update/click events
