ODF 1.1 has not specified the syntax of datatype 'angle'. Since ODF 1.2 it is specified as double with unit "deg", "grad" or "rad", or without unit. The unit-less value is specified to be in degrees. In all places, where LibreOffice reads angle values, it cannot read units. The cases where LibreOffice writes 1/10 of a degree values instead of degree are addressed in bug 161327. This bug report is for the cases where LibreOffice correctly writes unit-less values in degree, but is not able to read units. A list (hopefully complete) of those cases is in bug 161327#c8.
I have started work in https://gerrit.libreoffice.org/c/core/+/169360. It is not complete yet, but shows what I want to do. The still missing cases are: StartingAngle (chart), TextRotation (charts), RotateAngle (table cell), CharRotation, TextRotateAngle (custom shape), RotateAngle (extruded custom shape), Skew (extruded custom shape). CaptionAngle would be affected too, but its implementation is incomplete.

Not totally fixed, see the list in comment #1. But I will not have much time in the next days, so I've removed me from "Assigned".
