Is your feature request related to a problem? Please describe.
Frame levels between different groups are not coordinated. When creating WeakAuras that are displayed close to each other one can run into frame level issues with no way of fixing them.

Describe the solution you'd like
Infus mentioned that calculating frame levels recursively would fix this.

Describe alternatives you've considered
A hack to raise frame levels of sub elements is to add "empty" sub elements to a WeakAura until the desired frame level has been achieved (only for specific sub elements though)
