[Bug] Calling setStyle does not update storage, unlike setComponents

I'm configuring grapesjs in a way to allow users to edit the html and css source (by calling setComponents and setStyle respectively). There is an issue regarding the storeManager where the html is stored correctly, but the css is not. Here is a fiddle showing this: https://jsfiddle.net/szLp8h4n/189/

Steps to reproduce

1. Go into the linked fiddle
2. Run the fiddle
3. Open the "extended" code panels by clicking the 'Open code' icon in the top right corner (make sure the screen is wide enough that you can see it).
4. Change the html
5. Reload the page (or re-run the fiddle)
6. Notice your html changes were maintained 🙂
7. Re-open the "extended" code panels, now change the css
8. Reload the page (or re-run the fiddle)
9. Notice your css changes were not maintained 🙁
