Summary0004062: Incorrect behavior with Euler angles in Placement dialog
DescriptionWhen using Euler angles in Placement dialog, Roll angle is weirdly reset to 0° value.
This issue seems to be limited to Windows OS only.
No clue if all workbenches are affected or not ATM.
Both present on various 0.18 and 0.19 builds.

  4. In the Rotation group, choose "Euler angles" type then set Pitch=90° and Roll=90° and validate with OK
