Currently Ctrl X, Ctrl V changes ids of the elements

Plugin and Widget API Bugs
1

Designers are often moving elements around using Ctrl X, Ctrl V.
I suggest handle it as a special case and keep existing Ids.
It will help all plugin developers who rely on these ids.

Create new Figma file
Create new text element
In console run Figma.currentPage.children[0].id >>> “9:5”
select text element
Ctrl + x, Ctrl + v
In console run Figma.currentPage.children[0].id >>> “9:6”
The expected result was to receive the same element Id
