Edit pixel icons in webUI

[rknotter]

Hi
I can't find a way to edit an existing icon in the webUI? If I paste the existing array in the text field nothing happens unfortunately. The draw field is not updated. Tried chrome, firefox and even edge...
Am I missing something or is this not possible?

Thanks all!

Now, it does not work.
Also interested in this feature.
