[LiveComponent] data-live-ignore and nested elements

[norkunas]

Currently when using data-live-ignore on an element, it will be ignored from re-render and also it's all child elements also will be ignored.

I have an use case with a modal, where I have a live action which triggers re-render and I would like to keep the modal open, but that the form in the modal would be re-rendered.

I was wondering if someone would ask for this :). Yes, this seems reasonable - Livewire also has something like this.

See #519 for the proposal. For a modal, you would use <div data-rerender="children">. This would mean that the parent component is "ignored", but then children re-render via the normal mode of "diffing" the old and new elements via morphdom.
