This issue is a bit complex, as it affects core functionality of our editor.
As we’re planning to enhance the editor in the future™ I honestly can’t tell if it makes sense to touch this issue before hand.
Please don’t get me wrong here. 
Yes and no. We’re priotizing issues from paying customers.
That normally should speed up fixing issues, however, right now we have a bit more on our list.
That’s why I’m not sure if we’re able to have the desired effect on your side.
While it always helps Zammad as product to have paying customers in any way, I don’t want to make promises we might be able to keep up with.
I hope you get what I mean.
