:mattwoodrow, could you have a look please?

For more information, please visit auto_nag documentation.

Hi Markus, would you be able to have a look at this? I can get a Pernosco trace with layout.display-list.dump-content=true to help.

A Pernosco session is available here: https://pernos.co/debug/zgbQe-Uw-Nba0fH_vPkhYg/index.html

Fixed by bug 1729581, but will add a crashtest.
