Pandoc fails to convert embedded TEX formula

[Yuri05]

Translation.md contains the inline TEX formula Eq. 1: ${\Huge GMFE = 10^{\frac{\sum(|log(\frac{Pred}{Obs})|)}{n}} }$ which is properly displayed in MD:
Eq. 1: ${\Huge GMFE = 10^{\frac{\sum(|log(\frac{Pred}{Obs})|)}{n}} }$

However when converting it to Word via pandoc I get the following:

pandoc --from=markdown+tex_math_dollars+superscript+subscript+raw_attribute -t docx -o output.docx Translation.md
[WARNING] Could not convert TeX math {\Huge GMFE = 10^{\frac{\sum(|log(\frac{Pred}{Obs})|)}{n}} }, rendering as TeX:
  {\Huge GMFE = 10^{\frac{\sum(|log(\frac{
         ^
  unexpected control sequence \Huge
  expecting "%", "\\label", "\\tag", "\\nonumber" or whitespace

and the formula is not properly erendered in Word: output.docx

Have tried it with the latest pandoc version 3.1.2 - same.
Any ideas how to fix?

@pchelle I think it's a pandoc limitation in translating TEX and nothing we can do about it.
Maybe it's somehow possible to tell pandoc "just ignore unknown TEX instructions and proceed anyway"

Indeed, it seems that the translation limits to Math TeX only.
Thus, no LaTeX tags setting fonts seem to work.
I have tried to convert manually to raw openxml but I did not succeed in displaying the equation.
I also tried to set the style of the reference document but did not find where the equation style could be defined.

Last tested with pandoc 3.1.11 (released 16.12.2023) - still cannot be rendered.

LaTeX to OMML (word math langage) Pandoc conversion supports only the main LaTeX math package(s): jgm/pandoc#9403
I haven't found the list of LaTeX packages that are actually supported though
