Sharing proposal with a link is not possible on touch screens

1. What went wrong? When using a narrow touch screen device, the share link for a proposal is not completely visible and cannot be copied in the modal window. This is emphasized in the attached screenshot. 2. What did you expect to happen? I would expect the share link to work with touch screen devices. 3. Where did you find this bug? Default Decidim theme at Metadecidim. 4. What to do? I would suggest putting the share link to a form input element and creating a button that allows user to copy the link.
