This is so tricky that it really demands test coverage; we need to figure out how to test this in an automated way. I’m really concerned that we will break this in the future.

Should run the sort-export-file script. I’m pretty sure that this will sort lower in the file, because it’s a literal ASCII sort, so 9F will come after 10.

We want to initialize this to false above in the default constructor too.

I worry about the use of rounded in all the various cases like this, but I suppose it’s not new. Is rounding correct as opposed to ceiling or floor?

FrameView

Can you explain the "now gets two chances" here in the change log?

You forgot to initialize this in the constructor.
