Links behave unexpectedly when enchanting with (text-indent:) in header

With the following as a header passage,

(enchant: ?passage's lines, (text-indent: 30))

links in regular passages behave oddly. For example, the following code

[[first]]ly second [[third->test]] fourth

first [[second]]ly third [[fourth->test]] fifth

first se[[cond]]ly fourth fifth

outputs

Similarly,

Lorem ipsum dolor sit amet, [[consectetur adipiscing elit]]. Aenean vel tempor quam, vel porta tortor. Sed sapien elit, suscipit id tortor a, sodales iaculis erat. Donec suscipit eros vel nunc dictum, eget tristique enim vestibulum. Nulla facilisi. Aenean at lorem ac nulla condimentum scelerisque vel sed magna. Integer ac dui ac nisi mollis varius. Suspendisse potenti. Duis ex metus, rutrum sit amet dignissim sed, bibendum eu diam. Suspendisse sit amet urna non justo consequat ultricies ac ac turpis.
Cras ut diam accumsan elit imperdiet finibus nec consectetur libero. Integer lacinia erat ut ipsum volutpat, id eleifend nisi porta. Nulla sollicitudin risus rhoncus mi [[maximus facilisis]]. Quisque mauris risus, suscipit eget gravida ac, euismod nec mi. Donec pretium, urna ac rutrum facilisis, dolor ex fringilla augue, eleifend ullamcorper velit sem id felis. Donec pulvinar purus in tortor interdum posuere. Suspendisse malesuada dapibus velit sed interdum. Praesent ex nisl, malesuada ut vestibulum faucibus, rutrum in neque. In eget tellus nunc.
