Bug report

Bug summary

Setting "lines.markeredgecolor" in rcParams affects the ticks' mark color too. This is unexpected I guess.

Using "axes.prop_cycle" and the cycler label "markeredgecolor" produces the expected result, that is, it only changes the marker edge color and not the ticks' mark color.

Code for reproduction

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

matplotlib.rcParams["lines.markeredgecolor"] = "red"

x = np.linspace(0, 10)
plt.plot(x, x**2, marker="o")
plt.show()

Actual outcome

The ticks' mark color has turned red, together with the marker edge color.

Expected outcome

The ticks' mark color should ramin to its default value.
