The styleModifier variabile keeps previous values

[dharmastyle]

I am using Pattern Lab Node v2.3.0 on Mac, with Node v6.2.2, using the Gulp Edition.

Expected Behavior

When looking at a single pattern, the styleModifier should be empty (or ignored).

Actual Behavior

When styleModifier is used in a page to modify an included pattern, the single pattern inherits that styleModifier instead of being clean.

Steps to Reproduce

1. create a pattern #1 with a styleModifier
2. include it in a new pattern #2 and set a styleModifier for the #1 pattern
3. compile
4. browse to the single pattern #1
5. it will have the styleModifier set in #2 instead of being clean

I've uploaded my test case which shows this functionality working as designed.
Please tell me if I have you reproduction wrong, or (better) supply your own.

Hi,

@bmuenzenmeyer, to see the bug in action you should put the modified pattern as the last of the patterns that use that particular include.

I'm having the same problem and to see the bug in action I created these patterns:

01-button.mustache
<div class="button {{styleModifier}}">Button</div>

02-include-mod.mustache
<p>This is a pattern with a modified pattern included</p> {{> atoms-button:button--mod}}

But then, if you add a third pattern without modification the bug disappears

03-include.mustache
<p>This is a pattern with a pattern included</p> {{> atoms-button}}

In your example you should put the modified button in "Zzanother" to see the bug.

I can confirm this bug - mods going down to atoms.

@gfnool thanks for the additional steps - I've reproduced now. Should be easy enough to catch with a unit test and then fix.
