Auto completion can't suggest string enums correctly in Flow Style content.

[chuyangguangshin]

When write a piece of yaml in flow style, Auto completion can't suggest string enums.

Here is a demo:

while in indent mode, it can suggest right choices:

However, if you already input some characters , the suggestion just works again event in flow style :

schema.json used in the demo:

{ "$schema": "http://json-schema.org/draft-07/schema", "type":"object", "properties": { "A" : { "type" : "string", "enum": [ "a1", "a2" ] }, "B" : { "type":"string", "enum": [ "b1", "b2" ] } } }
