How to select overlapping elements more prominently

[maxming2333]

I found that the borders of many elements overlapped in the project, especially when I used mjml.
Because I set the padding margin of the elements to 0, the borders of many elements overlapped.

Now I hope that one of the components will be selected first in the editor if it overlaps.
For example, if I set attribute [data-se-type="foo"] for a component, as long as I recognize this attribute, then will be selected first

Of course I don’t want to disable the selection of other overlapping components

How can this be achieved?

This is similar to adding a z-index to a component. When selecting, the priority is calculated based on the z-index.
