generic matrix inversion yields incorrect results ovec RealBallField

[mezzarobba]

Steps To Reproduce

sage: b = RBF(0, 1e-1)
sage: mat = matrix([[b,b],[b,b]])
sage: ~mat
[1.000000000000000                 0]
[                0 1.000000000000000]

Expected Behavior

sage: ~mat.change_ring(CBF)
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
Cell In[7], line 1
----> 1 ~mat.change_ring(CBF)

File ~/co/sage/src/sage/matrix/matrix_complex_ball_dense.pyx:546, in sage.matrix.matrix_complex_ball_dense.Matrix_complex_ball_dense.__invert__()
    544         return res
    545     else:

    547
