   A modified version of the text rotation example shows that the bbox is at the correct place but the text is not rendered in the correct position relative to the bbox:

   

   import matplotlib.pyplot as plt
   from mpl_toolkits.axes_grid1.axes_grid import ImageGrid
   
   
   def test_rotation_mode(fig, mode, subplot_location):
       ha_list = ["left", "center", "right"]
       va_list = ["top", "center", "baseline", "bottom"]
       grid = ImageGrid(fig, subplot_location,
                        nrows_ncols=(len(va_list), len(ha_list)),
                        share_all=True, aspect=True, cbar_mode=None)
   
       # labels and title
       for ha, ax in zip(ha_list, grid.axes_row[-1]):
           ax.axis["bottom"].label.set_text(ha)
       for va, ax in zip(va_list, grid.axes_column[0]):
           ax.axis["left"].label.set_text(va)
       grid.axes_row[0][1].set_title(f"rotation_mode='{mode}'", size="large")
   
       if mode == "default":
           kw = dict()
       else:
           kw = dict(
               bbox=dict(boxstyle="square,pad=0.", ec="none", fc="C1", alpha=0.3))
   
       # use a different text alignment in each axes
       texts = {}
       for (va, ha), ax in zip([(x, y) for x in va_list for y in ha_list], grid):
           # prepare axes layout
           for axis in ax.axis.values():
               axis.toggle(ticks=False, ticklabels=False)
           ax.axvline(0.5, color="skyblue", zorder=0)
           ax.axhline(0.5, color="skyblue", zorder=0)
           ax.plot(0.5, 0.5, color="C0", marker="o", zorder=1)
   
           # add text with rotation and alignment settings
           tx = ax.text(0.5, 0.5, 'yB',
                        size=20, rotation=90,
                        horizontalalignment=ha, verticalalignment=va,
                        rotation_mode=mode, **kw)
           tx2 = ax.text(0.5, 0.515, 'By',
                        size=20, rotation=90,
                        horizontalalignment=ha, verticalalignment=va,
                        rotation_mode=mode, **kw)
           texts[ax] = (tx, tx2)
   
       if mode == "default":
           # highlight bbox
           fig.canvas.draw()
           for ax, txts in texts.items():
               for tx in txts:
                   bb = tx.get_window_extent().transformed(ax.transData.inverted())
                   rect = plt.Rectangle((bb.x0, bb.y0), bb.width, bb.height,
                                        facecolor="C1", alpha=0.3, zorder=2)
                   ax.add_patch(rect)
   
   
   fig = plt.figure(figsize=(16, 12))
   test_rotation_mode(fig, "default", 121)
   test_rotation_mode(fig, "anchor", 122)
   plt.show()
   

   Edit: updated the code to run on recent versions.
