MathML linebreaks in MathJax 3

[Charlie Belinsky]

Hello,

The following MathML worked in MathJax 2 but not MathJax 3 (or, at least I cannot get it to work):

<math xmlns="http://www.w3.org/1998/Math/MathML">

  <mn>1</mn>

  <mspace linebreak="newline"></mspace>

  <mn>2</mn>

</math>

In MathJax 2.7.4 it outputs 1 and 2 on separate lines.

In MathJax 3.2.0 it just outputs 12 with no linebreak.

Is this something that has not been implemented in MathJax 3?  Or, is there something wrong with the code?  The code comes from the Equation Editor in our Content Management System -- so I cannot change it much.  The best I can do is use JavaScript to tweak it a bit.

thanks much,

Charlie
