Class "rw..." in preview source

[logrunner (Jon)]

Looking at the code generated by Elements, I can see various divs that contain class names like: rwA3D19D2A_DE6D_XXXX_B39F_XXXXXXXXXXXX or rw2139C866_XXXX_447E_94CD_XXXXXXXXXXXX etc.

I have added a bit of redaction (as I don’t know what they signify) just in case.
What do these classes do?

You don’t need to worry about them, they are just unique ID’s for the components, no harm in posting them here

We use the ID’s for some styling features and/or javascript interactivity
