Hacking in multiline serialization not working in Asset Pipeline 2

Hi there.

In asset pipeline 1 / 2019.2 I had a post processing script that would take a long string in an asset file and split it into multiple lines (manually, by rewriting the asset file) using the following syntax:

Code (CSharp):

1.   _multilineString: >
2.     this
3.     is
4.     a
5.     multiline
6.     string
7.   anotherVar: b

This is admittedly hacky, but would deserialize properly in the past. Currently, it looks like unity 2019.3 / asset v2 isn't obeying the YAML folded style format as it reads in the > character instead of treating it as folded style string.

Is this intentional and related to the asset pipeline 2 as I suspect? Perhaps its within unity 2019.2 to 3? Any help would be appreciated
