Description
Some integers (or strings?) are treated differently even though they look the same to me.
In each comment I've specified what the scope inspector reports the scope as.
Testcase:
test:
- test: 01 # constant.numeric.integer.yaml
- test: 02 # constant.numeric.integer.yaml
- test: 03 # constant.numeric.integer.yaml
- test: 04 # constant.numeric.integer.yaml
- test: 05 # constant.numeric.integer.yaml
- test: 06 # constant.numeric.integer.yaml
- test: 07 # constant.numeric.integer.yaml
- test: 08 # string.unquoted.plain.out.yaml
- test: 09 # string.unquoted.plain.out.yaml
- test: 10 # constant.numeric.integer.yaml
This is what it ends up looking like for me:

I'd expect them all to be the same; so either they should all be integers or they should all be unquoted strings. Right?
