Blender Version
Broken: 2.90.1 release, 2.91 alpha a4f8b2ad76

Short description of error
Clipping Region (Alt + B) can be used to hide parts of the view. This does not normally affect whether these areas can still be edited (e. g. in Edit Mode).
In Sculpt Mode, if a part is hidden using Clipping Region, and regular Axis Symmetry is used, it works as expected. (I.e. changes also show up on the hidden half.)

However, if used with Radial Symmetry is used instead, changes do not show up in the hidden region!

Exact steps for others to reproduce the error
SculptRadialSymmetry.blend

Axis Symmetry (works correctly)

Enter Sculpt Mode
Turn on X-Symmetry.
Press Alt+B and draw a rectangle, such that one half is hidden.
Sculpt a bit.
Press Alt+B again to disable clipping. Observe that changes have also been applied to the hidden half.

Radial Symmetry (does not work!)
6. Reload the file.
7. Enter Sculpt Mode.
8. Set the Radial Z Symmetry to '2'.
9. Press Alt+B and draw a rectangle, such that one half is hidden.
10. Sculpt a bit.
11. Press Alt+B again to disable clipping. Observe that changes have NOT been applied to the hidden half.
