Constant line height with superscript

The default for line-stacking-strategy= is max-height, hence the reason the lines are not stacked evenly.

Use line-stacking-strategy="font-height" in order to keep a rigid distance between the baselines of all text lines.

David Tolpin adds

Attribute 'line-height-shift-adjustment' controls whether subscripts and superscripts affect line heights. The default value for this attribute is 'consider-shifts', which XEP adheres to.

Set the value to 'disregard-shifts' to get uniform line spacing regardless of presence of subscripts and superscripts.
