Select cut off in clone/copy card dialog

[juliusknorr]

Hi all, there's an issue with the selected input field upon opening the dialog, possibly because it is activated before the component is rendered.
I think that this is easily solvable by not auto-activating the input. Which will also allow a better understanding of what this dialog does (Currently the open select blocks part of the dialog)
