Bug summary

When using Axes.indicate_inset/Axes.indicate_inset_zoom, it may be necessary to increase the size of edges in order to be visible. It is possible to change edge colour with edgecolor=... which affects both the frame and the connectors. However, using linewidth=... only affects the frame.

Code for reproduction

import matplotlib.pyplot as plt

fig, axs = plt.subplots(2)
for ax in axs:
    ax.plot([1, 2, 3])

axs[1].set_xlim(0.5, 1.5)
axs[0].indicate_inset_zoom(axs[1], linewidth=5)

plt.show()
