We have updated our extension Formatting of All Math Formulas to 0.1.9 version.
The extension allows you to change font and font size for all (or only for selected) Math formulas in your Writer, Calc, Draw or Impress document for one time.
In this version we fixed problem with change symbols from bold and italic to normal view after extension using.
We updated extension official page https://extensions.libreoffice.org/extensions/formatting-of-all-math-formulas.
