A table cell can have a cell-style which defines cell-properties, paragraph-properties and text-properties.
Currently loading order seems to be
1. Load cell-style
2. Load default paragraph style
Step 2 causes problems as it can overwrite properties from step 1
Steps to Reproduce:
To see the effect open a document from eg. https://bugs.kde.org/show_bug.cgi?id=244340
and notice how in the 4th table of the file, the text sizes of the table are replaced from sizes from default paragraph style.
Fixed with the style inheritance
