Hi everyone!
Recently we upgraded from 3.5 to 3.10 and I've noticed that blocks do not have collapse/expand buttons anymore. I've dig a bit into source code and found out allowuserblockhiding setting which is enabled but it's not being used in block rendering context (mustache, javascript) or I can't find it.
Is this feature of show/hide blocks still supported by 3.10 classic theme or am I doing something wrong?
Same thing with docking, also not rendering per block.
