[Bug]: vertical_axis not respected when rotating plots interactively

[Illviljan]

Bug summary

When setting ax.view_init(vertical_axis="x") the plot is initialized as intended but once rotating it a little the plot and ax._vertical_axis is reset to the default value.

Code for reproduction

x = np.array([0, 1, 2, 4])
y = np.array([5, 10])
z = np.array([100, 150, 200])
X, Y, Z = np.meshgrid(*[x, y, z], indexing="ij")
c = np.arange(0, X.size)

plt.figure()
for j, (a, e) in enumerate([(0, 0), (-60, 30)]):
    for i, vert_a in enumerate(["z", "y", "x"]):
        ax = plt.subplot(2, 3, j * 3 + 1 + i, projection="3d")
        pc = ax.scatter(X, Y, Z, c=c)
        # ax.view_init(vertical_axis=vert_a)
        # ax.view_init(azim=0, elev=0, vertical_axis=vert_a)
        # ax.view_init(azim=-60, elev=30, vertical_axis=vert_a)
        ax.view_init(azim=a, elev=e, vertical_axis=vert_a)
        ax.set_title(f"azim={a}, elev={e}, vertical_axis='{vert_a}'")
        ax.set_xlabel("x")
        ax.set_ylabel("y")
        ax.set_zlabel("z")

Actual outcome

Inital view:

After a small rotation on the bottom right plot:

Expected outcome

ax._vertical_axis should stay the same when rotating plots. This worked correctly in earlier matplotlib version.
