when I select "Rematerialize all" for an asset group, then select "Scaffold missing config", the Scaffold missing config confirmation text box appears behind the Launchpad window and is inaccessible until clicking away from the Launchpad window to make it disappear, rendering the scaffolding unusable (dagster==0.15.0, Firefox).

Yeah I also had this once mid demo, had to restart dagster

thanks for reporting this. @dish - is that what you fixed here? https://github.com/dagster-io/dagster/commit/eb399654992b6b15fd08049cd8feb640f7e02770

Yep! This will be fixed in the next release.
