Test failures with the development version of igraph

[krlmlr]

We're changing the layout of igraph objects. This leads to check failures in your package, see https://github.com/igraph/rigraph/blob/f-igraph-t-idx-revdepcheck/revdep/problems.md and igraph/rigraph#789 for details.

To reproduce, please install the development version of igraph via

# install.packages("pak")
pak::pak("igraph/rigraph")

and run R CMD check on your package.

We plan to release an igraph update on June 12, three weeks from now. Can you please send an update to CRAN that fixes the checks, or tell me that the failure is unexpected and we should be fixing this?

I can't run the tests with your package on macOS nor Ubuntu, I'm probably missing something. Thank you for your help!
