Not preserving lines around custom @-rules

[lynzrand]

Plugin version: 2.14.0 (tested in browser and VSCode plugin)

When formatting the following code in Stylus Supremacy:

@lost gutter 24px
@lost flexbox flex
default-font = 'Sarasa UI SC'

We get the following result (with default settings):

@lost gutter 24px;@lost flexbox flex;default-font = 'Sarasa UI SC';

Formatting without semicolons makes things worse:

@lost gutter 24px@lost flexbox flexdefault-font = 'Sarasa UI SC'

Expected output is the same with input (with semicolons).

This will be fixed in v2.14.2 or newer.
