This didn't cause any regression only because every place using these style contexts explicitly sets the state of the style contexts before use. In fact, the GtkTreeView style context is not used anywhere else, and the GtkEntry style context is only used in paintTextField, which does set the state before use (and then reverts it using save/restore), so this cannot have broken anything in practice. But it's a landmine waiting for the next programmer to trip it.
