Same error, same rustc version

Please file an issue on GitHub at triagebot if there's a problem with this bot, or reach out on #t-infra on Zulip.

[kpreid]

I don't have a MCVE but the same problem on the same nightly version happens with a dependency of luminance-glfw = "0.18.2". Sounds awfully similar to #103463 also involving luminance deps, but that one's definitely fixed.

[GuillaumeGomez]

Pinging @petrochenkov since they're the last one who worked on this. Maybe you have an idea?

[dhardy]

Somewhat minimal example: kas-mcve-rustdoc-no-entry.zip

Removing the Scrollable impl avoids the bug.

[dhardy]

This happens with beta too: rustc 1.66.0-beta.1 (e080cc5a6 2022-11-01)
