Short description of error
While in an axis-aligned orthographic view (top/bottom/front/back/left/right with any amount of camera roll) and sculpting with a Projected falloff tool, there is a deadzone surrounding the mesh where mouse inputs will have no effect on the mesh. Sculpting within the mesh's bounding box or outside the deadzone works as expected.

The deadzone when using a top orthographic view has been roughly indicated by using an extra red mesh placed below the mesh being sculpted.

The deadzone size does not change with the camera zoom level, so when sculpting large meshes, the deadzone will be small in comparison to the mesh and when sculpting small meshes, the deadzone will be large in comparison to the mesh.

The cube here is a 1m cube:

Exact steps for others to reproduce the error

Open the attached .blend, it is already in orthographic top view and in sculpt mode with the Grab tool set to constant Projected falloff
Click and drag the mouse cursor within the red area of the screen and outside the mesh's bounding box
Observe the mesh is unaffected by the sculpting
Click and drag the mouse cursor just outside the red area
Observe sculpting works as expected
Undo because moving the mesh moves the deadzone
Click and drag the mouse cursor in the red area that is within the mesh's bounding box
Observe sculpting works as expected

This seems to be problematic, was already reported/handled in #109555 but apparently still not right.

7f256e0d33 / 3004198866 / 0b01b7c1fa are relevant here

Ah sorry, was testing the wrong brush, so it is working in 4.0.0 onwards, which makes this a request to backport 7f256e0d33 / 3004198866 / 0b01b7c1fa
