(re: #5637, re: #5618)
This can happen if the user enters a value that is not matched to
one of the combo suggestions.
Also make sure to set `this` to the input field. It might not be
already if the event was triggered from a keypress instead of a click.
(closes#5690)
This change also makes sure to use the latest copy of the entity in
field.isAllowed() to ensure the prerequisite field check works
and fieldsArr is filtered properly for #5583
(closes#5568)
Several strategies in here:
- Move uiCombobox() from inside the render function to class variable
- Don't render stuff like the raw tag editor when it's collapsed
- Don't show as many fields/combos on hover
- Don't instantiate fields (like universal/more) until they're actually shown
- Bind the combo on enter selection not on update selection
Fixes issue with nested/namespaced fields, such as `maxspeed/advisory`,
in situations where would try to use a css selector or element id.
Can't use characters like '/' in a css selector.
This allows universal fields or other standalone fields to have a default value.
This didn't work before becuase default values were only handled by
preset.applyTags() / preset.removeTags().
