plotly.js: LaTeX/MathJax broken using Firefox v82.0

Hi Plotly team, I just recently updated my firefox browser to version 84.0.1 and have been using plotly’s (v4.14.1) subplots in Jupyter notebook (v6.0.3) with Python (v3.7.6) for a couple months now without issue. I noticed that with this new version of the browser when I call something like:

from plotly.subplots import make_subplots

fig = make_subplots(1, 3, subplot_titles=[1, 2, 3])
fig['layout'].update(width=1200, height=1200)
fig.add_trace(go.Scatter(x=[1 , 2 , 3], 
                             y=[1 , 2 , 3], 
                             name='$123$',
                            ),
                  row=1,
                  col=1
                 )

fig.add_trace(go.Scatter(x=[1 , 2 , 3], 
                         y=[1 , 2 , 3], 
                        ),
                  row=1,
                  col=2
                 )

fig.show()

The figures do not render properly and when I try to toggle the traces by clicking on the legend, all of the plots shrink and are illegible. This issue seems to be caused whenever I add Latex to the legend str using the name argument in go.Scatter while ALSO using the update command to manually set the width and height of the figure. If I do only one or the other, the behavior seems to go back to normal. It also seems to be unique to Firefox, as I did not have an issue with Chrome when I tested this with the same environment. Hoping this is enough information to create a reproducible example and solve this issue.
