I'd like to fix the formatting but I can't edit my issue.

Our team is also running into this because we use kotlin reflection to set up mock data for previews.

Can you suggest any workaround that we can apply locally to make layout lib include kotlin reflect until it is officially fixed? We are obviously including it as a build dependency but the layout lib preview doesn't pick it up for some reason.

I do not see this issue in Electric Eel Beta 4, but I do see it in Flamingo Canary 6.

I do not see this issue in Electric Eel Beta 4, but I do see it in Flamingo Canary 6.

Is it with the very same project? I'm trying to rule out whether this is related to specific library/compiler versions.

Thanks!
