Marking as fuzzblocker. The fuzzers are frequently hitting this issue.

This cause of the assert is likely specific to printing, so if your fuzzing harness supports it you could still report instances of this assert that don't involve printing.

In this case we are already doing so. With these buckets in place the fuzzer will still hit these issues (fairly frequently in this case). This causes unnecessary overhead and can block code paths from being explored. We also run the risk of making buckets that are overly inclusive.
That said we understand resources are limited. Some issues do not have direct impact on end users and other more important tasks may take priority.
We use [fuzzblocker]
to indicate that, from the fuzzing perspective, this is important since in many cases it is not obvious. Fixing fuzzblockers really helps unblock the fuzzing pipeline.

When actually printing, we create a temporary display list builder with
a reference frame which is the PrintedSheetFrame for the current frame:
So when building overflow from previous sheets, this assertion trivially
fails.
I don't think applying the offset even though the reference frame is the
printed sheet frame rather than the root frame is wrong, so remove the
assert to unblock fuzzers.
I tried to add the current test as a crashtest but it didn't repro on
trunk, so asking for another repro atm.

:emilio, since this bug contains a bisection range, could you fill (if possible) the regressed_by field?
