Bug 196215

Summary:	Web Inspector: Green highlight disappears from edited properties when adding a new property
Product:	WebKit	Reporter:	Nikita Vasilyev <nvasilyev>
Component:	Web Inspector	Assignee:	Nobody <webkit-unassigned>

# STEPS TO REPRODUCE:
1. inspect any page (https://devinrousso.com/demo/WebKit/test.html)
2. open the Elements tab
3. select any element that has at least one rule with at least two properties
4. disable (e.g. comment out) the first property of the rule with at least two properties
5. add a new property immediately after the first property
 => the green "modified" border/highlight next to the first property disappears

NOTES:
The problem is that properties get recreated (when they shouldn't be) and the recreated properties no longer have initialState.

Technically, this broke with https://trac.webkit.org/changeset/243256/webkit. However, reverting it is unlikely to be the correct solution.

This should be addressed by the patch in https://bugs.webkit.org/show_bug.cgi?id=195264#c17.
