LaTeX \boldsymbol command no longer works in MathJax?

[Sean Fitzpatrick]

I just noticed on this page that \boldsymbol no longer works in HTML.

(I've always found that \cdot feels too small for the dot product, so I use \boldsymbol{\cdot}.)

If this is no longer supported on MathJax I'll make a change.

(Fortunately this is a macro so I only have to change one line in source.)

I can't think of a change on our end.

Did you rebuild something really old? Change your docinfo?

Seems to require a package?

This seems to be a recent change on the MathJax end. I haven't noticed any problem in the past and this has been in my book for years.

I guess I need to either figure out how to load a package in MathJax, or choose a different symbol

Look in the sample article to see how the "cancel" package is used.

But maybe first ask on the mathjax-users Google Group?

Thanks. Maybe applying bold to a math symbol is not compatible with Braille, or accessibility generally?

I'd say it should just be ignored. ;-)

Adding <package>boldsymbol</package> to my <latex-preamble> seems to have done the job.

Although when your book is already in your browser cache, you need to do a hard refresh AND a regular refresh before it takes effect!
