BUG - Copy To Last Page causing setting errors

[alectroniq]

Does the issue occur in the electron-app or the web-app?

• midi-bricks-web-app
• both

Can you determine, which version was used?
Version: 1.3.27

Describe the bug
The "Copy To Last Page" function is causing errors on exisiting Elements. I experienced even the reversion of settings on about 12 elements, that I've made in their Settings dialogues before copying a single element to last page.

Desktop Version (please complete the following information):

• OS: Win10

Additional context
Reffering to #184 the whole Select & Copy function needs to be excluded before release and then maybe rewritten entirely.

Elements will now be copied to the maximum right or bottom end of the page, so no confusional distribution of the current elements can happen. See 1.3.39-alpha.10
