Rendering in repeating group

How does Bubble render invisible elements in a repeating group?
More precisely, when?

I’m considering adding the edit form for each row into the table row, and show/hide it by the “edit-button”. It will create a very nice interface. The edit form is in a reusable element.

But what are the consequences? Will it slow the repeating group?

Best regards

Anyone from Bubble that can answer this?
See that the new “experimental” rendering does some optimizations, but does not really answer this question.
