Description

when testing size assistant with fields coming from a join , named with a prefix initialized with layer name I faced a small bug:

layer name: label44 copier
field prefix for joins: label44 copier
field name once joined: label44 copier_attr
expression output from size assistant:

coalesce(scale_exp(label44 copier_attr, 1, 2, 1, 14, 0.57), 0)

That expression is not correct, when it should be 
coalesce(scale_exp("label44 copier_attr", 1, 2, 1, 14, 0.57), 0)

This is a edge case but can happen. Quoting field names will prevent that
