ipython.display Markdown not rendering in voila like it does in jupyter lab

Here is the code to reproduce:

from IPython.display import display, Markdown
import ipywidgets as widgets
from ipywidgets import interact

def explainer(num):
    print("The number guessed it: ", num)
    print("")
    print("The formula to use is: ")
    display(Markdown("$\;\;\;\; \\frac{2x+8}{2}-x$"));
    print(f"Substitute the number in for x, in this case {num}")
    display(Markdown("$\;\;\;\; \\frac{2 \cdot %s +8}{2}-%s$" % (num, num)));#.format(number = num)));
    print("Simplify:")
    display(Markdown("$\;\;\;\; \\frac{%s +8}{2}-%s$" % (num*2, num)));#.format(number = num)));
    print("Simplify:")
    display(Markdown("$\;\;\;\; \\frac{%s}{2}-%s$" % (num*2+8, num)));#.format(number = num)));
    print("Simplify:")
    display(Markdown("$\;\;\;\; %s-%s$" % (int((num*2+8)/2), num)));#.format(number = num)));
    print("Simplify:")
    display(Markdown("$\;\;\;\; %s$" % (int((num*2+8)/2) - num)));#.format(number = num)));
    #print(display(Markdown(r"$\frac{2x+8}{2} - x$")))
    print("The result of the computation is: ", int(qa(num)))
interact(explainer, num=widgets.IntSlider(value=4, min=0, max=100));

On the left you will see the rendering in jupyterlab, on the right is voila:

Note: This issue seems to be inconsistent, most of the time It does not render properly - but I have seen it render properly a couple of times. But in the instances where it did render properly on page load - it 100% of the time does not render properly after having dragged the slider.
