Matplotlib/v-3.4.2 problem with latex preamble in matplotlibrc

Question

I have matplotlibrc file which contains following for latex preamble

text.latex.preamble : \usepackage{siunitx}, \usepackage{amsmath}, \boldmath

This definition used to work with matplotlib/v-3.03, but when I updated to version-3.4.2, it stopped working. I checked the cached tex file that matplotlib created, I found that in version-3.4.2 it can not split preamble properly. I am showing respectively lines from tex file bellow

Version-3.0.3

\usepackage{siunitx}
\usepackage{amsmath}
\boldmath

Version-3.4.2

\usepackage{siunitx}, \usepackage{amsmath}, \boldmath

Can someone help me, the right way to define the preamble in matplotlibrc file for new version? I know they have changed how to handle preamble but could not figure it out.

Thanks

Can you try without the colons in your matplotlibrc? The missing line breaks should not be a problem for latex — samcarter_is_at_topanswers.xyz

@samcarter_is_at_topanswers.xyz thanks a lot. It worked. I think you mean comma — Masrul Huda Parvez

yes, you are totally correct, I meant comma. Was a bit a late yesterday when I wrote that :) — samcarter_is_at_topanswers.xyz

Can you write a self-answer? I'm not a matplotlib user, so can't test any code and this was just a wild guess. — samcarter_is_at_topanswers.xyz

As suggested by @samcarter_is_at_topanswers.xyz, if I remove the commas from the preamble, it works for both the old and new versions.
