Note: If you have previously installed a version of Cascadia Code, please uninstall the previous version prior to installing a new version. Not doing so can result in improper rendering.

Thanks for filing! We're going to use this bug to track ingesting the new version of CascadiaCode into Terminal in the next round of updates so that this issue won't occur.
