Change width of "zero effect line" in plot_model() function

[eimichae85]

Hi there,
Is it possible that after the update the gray zero effect line in the plot_model() function got narrower by default?
A year ago the zero effect line defaults looked like this:

Yet when I recently created a plot the zero effect line is much narrower

Is it possible to manipulate the zero-effect line size (I want it to look like the older, wider line again).
I guess somehow via the vline() function? But how?

Thanks
M.
