Comment:

 This appears to be fixed in 8.2 with `vector-0.12.0.0`. Unfortunately,
 it's quite unclear what fixed it and working this our will likely be a
 significant investment of effort.

 Given that there is unlikely to be an 8.0.3, I think it's pretty unlikely
 that we will fix this in the 8.0 series but I'm marking this as `merge`
 regardless.
