plot shrinks faster than x_axis when changing x_range

Description of bug / unexpected behavior

When plotting a function in an axis environment, if the x_axis range is changed using a ValueTracker, and the same ValueTracker is used as function range, the function does not plot on the expected range. Here is a MWE:

from manim import *

class VaryingSupportSineWave(MovingCameraScene):

    def construct(self):

        x_max = ValueTracker(10)
        ax = always_redraw(lambda: Axes(
            x_range=[0, x_max.get_value(), 1],
            y_range=[-1, 1, 0.5],
            x_length=x_max.get_value()
        ).to_edge(LEFT))
        self.add(ax)

        sine_wave = always_redraw(lambda: ax.plot(lambda x: np.sin(x),
                                                  x_range=(0, x_max.get_value())))

        self.play(Create(sine_wave))
        self.play(x_max.animate.set_value(6))
        self.wait(0.5)

Expected behavior

the axes are drawn and the x_axis is ten units wide
the sine wave is added and plotted up to ten units
the x_axis shrinks down to six units, each unit is still one munit wide (no scaling effect, the axis only gets shorter), and the sine wave is now drawn also on only six units

Actual behavior

the axes are drawn and the x_axis is ten units wide
the sine wave is added and plotted up to ten units
the x_axis shrinks down to six units, each unit is still one munit wide (no scaling effect, the axis only gets shorter), BUT the sine wave is now drawn on only about 3.5 units, and it has been scaled down!
