Inconsistent OSF in Table of Contents using Microtype, LuaLaTeX and Tocstyle [closed]

Question

My table of contents should have the following properties:

• oldstyle figures for page numbers and labels
• chapter entries in spaced, lowercase smallcaps
• numbers close (en-space) to the entries, no dotfill

You should be able to see in the MWE that oldstyle figures are produced for all labels and the page-numbers of the sections, but not for the page numbers of the chapters.

The oldstyle figures appear, if I comment either the

• lsstyle command or the
• \usetocstyle{nopagecolumn}

Both indicated in the MWE. As shown in the MWE-chapter Introduction, the combination (lsstyle, scshape, lowercase) works in normal text and produces oldstyle figures.

Please note

• there are some problems when setting letterspaced smallcaps with LuaLaTeX. This is why I use the setting \addfontfeature{Renderer=Basic}.)
• you need Microtype2.5 to reproduce the problem
• the problem may be related to this tex.SE entry
