Bugmon Analysis
Testcase crashes using the initial build (mozilla-central 20210615134418-4bf424b6f46a) but not with tip (mozilla-central 20211203213802-92df9c655be5.)
The bug appears to have been fixed in the following build range:

Start: f5cb6b2465f3042f3ec5bb096a75fbe24f71465e (20211116073345)
End: 5d32dbafda59a62fba936250375782a4cc9c6300 (20211116082732)

That "fix range" includes Bug 1669149 which inadvertently broke window.print() in fuzzer builds (an issue that was tracked & later fixed in bug 1741698).

So I suspect this is still reproducible. jkratzer, would you mind confirming that this still repro's in up-to-date builds? (And if possible, maybe getting a pernosco trace?)

Severity: -- → S3
Flags: needinfo?(jkratzer)

(I'm calling this S3 since I assume there's not an exploitable issue (or a user-visible-in-reasonable-web-content issue) here. GetEffectiveRowSpan simply returns 0 in opt builds (after this MOZ_ASSERT_UNREACHABLE statement) which I think is intended to provide graceful/trivial fallback behavior.)
