Description

Sometimes, when repeat()ing a gradient and retrieving the new gradients stops, it's not possible to feed them back into a gradient constructor.
MWE:

#let my-gradient = gradient.linear(red, blue).repeat(5)
#gradient.linear(..my-gradient.stops())

The error message is "Offsets must be in strictly monotonic order".

Most interestingly, this only happens with 7,9,10,11,12,13,... repetitions. Moreoever, if the stops are hover-inspected and copied to a variable explicitly, like

#let stops = (
  (rgb("#ff4136"), 0%),
  (rgb("#0074d9"), 20%),
  (rgb("#ff4136"), 20%),
  (rgb("#0074d9"), 40%),
  (rgb("#ff4136"), 40%),
  (rgb("#0074d9"), 60%),
  (rgb("#ff4136"), 60%),
  (rgb("#0074d9"), 80%),
  (rgb("#ff4136"), 80%),
  (rgb("#0074d9"), 100%),
)

#gradient.linear(..stops)

the issue vanishes. For this reason I assume that due to floating point errors, some offset values end off lower than others.

One a side note, looking at line
