Should be closed by #117?

@StevenClontz beat you to this, silly copilot!

[StevenClontz]

Not sure why this was opened TBH, didn't it also suggest the same changes in the PR directly? Why would this also be necessary?

[oscarlevin]

When you ask copilot to fix multiple suggestions as a batch, it submits a PR to the original pr.

[StevenClontz]

Still weird as this doesn't point to the PR but to main. But I suppose not really important.
