It probably only auto focuses when the element is created, so it may only work if the element is created after the dialog is show. But if they dialog renders the html when it's created (not shown) then it won't work. The dialog needs to render the editor when it's shown, you man be able to do that yourself with a simple #if

Tried using an #if to ensure the dialog would be rendered anew when loading; didn't work. Tried getting the input element and calling .focus() on it; didn't work. Will give up for now and tackle a different issue, and maybe come back to this one on another day when I might have fresher ideas.

looks like there's a bug in svelte-ux, I've implemented a workaround for it

Looks like it's working now. Rebased on top of latest develop to test, then I'll mark the PR ready for review if it continues to work after rebasing.
