Description
Setting one root works well:
sc.pl.paga(adata, layout='eq_tree', root=[9])
Setting multiple roots returns an error:
TypeError: unhashable type: 'list'
Please give an example for using multiple roots, and also explain what does rootlevel= set?

Research direction
Start by reproducing the sc.pl.paga call with layout='eq_tree' and multiple roots, comparing it with the working root=[9] example. Trace how root and rootlevel are handled, then document a working multiple-root example and explain what rootlevel controls; verify that the reported TypeError is resolved.
