[mathjax] enable chtml since v3 updated to v3.2

[mmcky]

See if chtml can be used instead of svg for math rendering

[mmcky]

@shlff @AakashGfude this chtml looks really nice now -- if you had 10 minutes would you mind taking a quick look at a few pages and let me know what you think.

mathjax released version 3.2 -- @AakashGfude can you confirm which mathjax version is loaded on the preview.

This is looking pretty good -- even handles the long equations in

well.

[mmcky]

@AakashGfude I think I figure it out with web inspector

e.mathjax = {
                    version: "3.2.0",

so 3.2 is loading 👍

Nice work @mmcky .

well.

Thanks @mmcky . They look nice to me.

I guess this long equation is a bit so long that we could also modify the code a bit.

Additionally I notice that the horizontal lines in a fraction and a square root are missing. Will we fix that as well? e.g., the following:

[mmcky]

@shlff nice work! I didn't see the missing horizontal lines but that is a problem still!

Might need to investigate this before we switch to chtml

these are now working with chtml so we should be able to turn svg off soon.

There are now a lot of matplotlib deprecation warnings though :-(

[shlff]

Thanks @mmcky . Those warnings are raised because the following four functions or class were deprecated in Matplotlib 3.4 and will be removed soon in matplotlib:

• to_png
• to_rgba
• to_mask
• MathtextBackendBitmap

I will try to search for their substitutes and see if I can remove these warnings. I will keep you posted here later.

@jstac the font size for math in chtml seems a bit bigger than under svg. Interested in your thoughts for the inline math (in particular).

[mmcky]

chtml has been enabled so this is no longer required.

@shlff I have checked the test case you mentioned above and it looks nice now.
