Thanks a lot for the PR!
Although this resolves the issue as mentioned in #5708 it doesn't provide a complete refresh method. Refresh should allow to change all options on-the-fly (theme, mini, clear button text, etc.). What we probably need to do here is move code from the create method to a new refresh method and have the former call the latter.
Do you feel like working on a PR for that?

Thanks!
