Description

The settings of layer's feature rendering order appear to randomly fail when zooming / panning around the QGIS' canvas. See attached screencast (bug.mp4).

Steps to reproduce
  1. Create a new project
  2. Add a vector layer dataset with feature overlap(s) which can be sorted to be above / below one another
  3. Activate the [x] control feature rendering order, sort by a given column (in the above screencast, I'm sorting a text column)
  4. Click on the [ Apply ] button (* live update doesn't work with rendering order)
  5. Start panning around, notice the rendering order is randomly failing

More on this: the issue has to do with sorting of a field which name is an expression engine function (i.e. field name YEAR, expression function year()). The code must fail to put the field name in between "quotation marks".

Is that fixed with https://github.com/qgis/QGIS/pull/3269 ?
