I will contact Elementor but do you not think it is better if you contact them? Especially if you consider the problem as I described as a "problem" as well. Because, if you do so then it becomes problem which affects Toolset not only me and you will be in a better position to talk to Elementor people.
We can contact and our compatibility team can be in touch but it will be a relatively slow process. We always recommend that users should raise the issue to that will help users to push things quickly. Another thing is that It's a small thing and there is a workaround so we are not sure if they give much emphasize on such things as if you create and raise it you will have soon clear picture about if its going to supported in near future or do have plans to add it or you should keep using workaround.
I will raise the issue with them but I think your importance is higher compared to mine in their eyes. You are sort of a partner and I'm a simple user.
