Bug summary

get_tick_params on xaxis shows yaxis keywords

Code for reproduction

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

print(ax.xaxis.get_tick_params())

Actual outcome

{'left': True, 'right': False, 'labelleft': True, 'labelright': False, 'gridOn': False}

Expected outcome

{'bottom': True, 'top': False, 'labelbottom': True, 'labeltop': False, 'gridOn': False}

Additional information

The current implementation of get_tick_params tries to invert the keymap dict which is impossible because this dict is a 1:n relationship (multiple keys with the same value).
This went unnoticed because the test_axis_get_tick_params didn't actually test anything: the expected value is calculated in the test using the very same algorithm as the function under test.
