Description

When activating "control feature rendering order" in the vector layer symbology settings, the order can be correctly controlled by values in a normal field. If a virtual field is selected, however, rendering order ist not changed according to the field values.
An example project and shapefile are attached. When selecting the normal field "priority" in the control feature rendering order dialog, the order of the two polygons can be reversed by switching the sort order. When the virtual field "virtual" is selected, the rendering order does not change.
Testet on Windows with Version 3.4.1 and Master (3.5.0, code version 152b1b09ff).
