Dexxor added a comment to T386071: <math>_1</math> not rendered as subscript.

Another related bug: The "i=0" in <math>\min\limits_{i=0}</math> should be rendered below "min" but it's not.

Dexxor added a comment to T386071: <math>_1</math> not rendered as subscript.

A possibly related bug is that the "2" in <math>\sin \cos^2</math> or <math>\deg \cos^2</math> is not rendered as a subscript (i.e. I would expect to see "sin⁡ cos²" but it actually renders as "sin⁡ cos⁡2"). Again, "Invalid markup: Incorrect number of children for <msup/> tag" is printed to the Firefox console. Interestingly, <math>\sin^2 \cos^2</math> is rendered correctly as "sin⁡² cos²".
