Code for reproduction

import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns

data = np.random.rand(10, 10)
sns.heatmap(data)
plt.show()

Actual outcome

Initial result on the Y-axis is from 9 to 0
After Home/H is pushed it will reverse the order from 0 to 9

Expected outcome

It should not reverse the order of Y-axis value
as tested on matplotlib 2.0.2
