Description

[Description of the issue]

YAML highlighting for a key's value continues onto the next line when it is a simple, non-quoted string (not a list, another key, a multiline string (with | or >), etc, and the highlighting should not continue.

Simple test case in YAML file to reproduce

this: key
is
highlighted
over
arbitrary
number
of
lines

Expected behavior: [What you expect to happen]
When using a simple, non-quoted string in YAML, I expect the next line's content to not be highlighted unless it is a quoted string, a list, a multiline string (with | or >), etc. In the example, 'is' begins a line that violates YAML's syntax. One suggestion that this case is the correct one is that trying to load a test yaml file in Python with the text will throw an error with the text could not find expected ':' on the example line "is".

Actual behavior: [What actually happens]
YAML highlighting for a key's value continues onto the next line when it is a simple, non-quoted string (not a list, another key, a multiline string (with | or >), etc. See image below.

Reproduces how often: [What percentage of the time does it reproduce?]
Always
