Context manager for plots is not working with dicts

Description

It seems like the plot functions work in combination with_pyfar.plot.context()_ (and matplotlib.style.context()) with styles as input:

import pyfar as pf
import matplotlib as mpl
import matplotlib.pyplot as plt
pf.plot.use()

with pf.plot.context('classic'):
    fig, ax = plt.subplots(2, 1)
    pf.plot.time(pf.TimeData([0, 1, 0, -1], range(4)), ax=ax[0])
    ax[1].plot(range(4), [0, 1, 0, -1])

But not with dicts as arguments:

import pyfar as pf
import matplotlib as mpl
import matplotlib.pyplot as plt
pf.plot.use()

with pf.plot.context({'lines.linestyle': ':'}):
    fig, ax = plt.subplots(2, 1)
    pf.plot.time(pf.TimeData([0, 1, 0, -1], range(4)), ax=ax[0])
    ax[1].plot(range(4), [0, 1, 0, -1])

I suppose the reason is that for example the linestyle is overwritten by the call of pyfar.plot.context() within the plot function. In constrast, this works well:

import pyfar as pf
import matplotlib as mpl
import matplotlib.pyplot as plt
pf.plot.use()

style = {'lines.linestyle': ':'}

fig, ax = plt.subplots(2, 1)
pf.plot.time(pf.TimeData([0, 1, 0, -1], range(4)), ax=ax[0], style=style)
ax[1].plot(range(4), [0, 1, 0, -1])

We discussed that there is not really a solution without calling the plot functions with a style=... parameter.
This includes the solution for avoiding all properties of the pyfar plot styles by calling with an empty dict style={}.
