picker-indicator resizes when Colorpicker is appended somewhere else

[webketje]

Hi,
First off, kudos to making the simplest & sleakest color picker available out there.
In order to avoid creating color pickers for every color setting on a page, I wanted to use 1 color picker & move it to every setting once clicked. However, the picker-indicator is disproportionately resized when this is done (I don't really get why it is resized at all).
This is what it looks like after being moved:

My temporary solution is to set .picker-indicator { width: 1px !important }.. What causes this?
