Output differ form Mathjax 2.7

[senthilsam]

Hi,

I am converting the below mathml to svg using both 2.7 and latest mathjax,

<mml:math><mml:mrow><mml:mi>d</mml:mi><mml:mi mathvariant='bold-script'>l</mml:mi></mml:mrow></mml:math>

When I render the output in browser both are same. but when i edit and see the svg, the new one generated has tag in it. however the one generated using 2.7 doesn't have.

Output form 2.7:
