1664488 - Disable various preferences for deprecated MathML features

Status: RESOLVED FIXED

(Core :: MathML, task)

Description

[Frédéric Wang (:fredw)]

I would try to disable these:

mathml.deprecated_style_attributes.disabled
mathml.deprecated_menclose_notation_radical.disabled
mathml.mathsize_names.disabled
mathml.mfrac_bevelled_attribute.disabled
mathml.deprecated_alignment_attributes.disabled
mathml.script_shift_attributes.disabled
mathml.xlink.disabled
mathml.mfrac_linethickness_names.disabled

user counter statistics is zero, but I'm not sure how to get data for release or to compare against mathml.doc_count

I would hold off for

mathml.mathspace_names.disabled
mathml.stixgeneral_operator_stretching.disabled

I know some tools use *mathspace names (at least MathJax and Wikipedia; not sure if that's still the case) and we still don't know whether Apple would preinstall STIXTwo on mac soon.

This commit disables the following preference on all builds by default:

mathml.deprecated_style_attributes.disabled
mathml.deprecated_menclose_notation_radical.disabled
mathml.mathsize_names.disabled
mathml.mfrac_bevelled_attribute.disabled
mathml.deprecated_alignment_attributes.disabled
mathml.script_shift_attributes.disabled
mathml.xlink.disabled
mathml.mfrac_linethickness_names.disabled

In addition, the following one is disabled on all but mac platform,
where currently (macos catalina) STIXGeneral is still the only
pre-installed math font available:

mathml.stixgeneral_operator_stretching.disabled
