Layers Manager doesn't work with several editors

Hi again! As I comment in a previous question, We're working with several editors in the same window. The issue we're facing now is that layer manager doesn't work fine when I go from one editor to another. These are the steps that make this problem happens:

1. Editors initiated
2. Go to Layer Manager inside editor 1 (click on layers icon) - everything ok

3. Open editor 2 and click on layers icon - looks like this:

I saw that the library is adding the prefix "gjs-" on components that already have this prefix:

To fix it provisionaly, I changed this line inside javascript code "config.layers.stylePrefix = config.stylePrefix + lyStylePfx;" to "if (lyStylePfx.substring(0,4) != "gjs-") config.layers.stylePrefix = config.stylePrefix + lyStylePfx;". With this now it's working fine, but there may be a better solution.

Please, let me know if there is another way. Thanks!
