This commit allows you to change the icons of custom links of the social media block after the first save. Thanks to [this other commit], there is now a class that permits to inform the editor that a media is editable even if it is a non-editable parent. This commit permits to use the new class to fix the issue. Steps to reproduce the bug: - Drop a social media block on a page - Add a custom social media - Save - Edit - Try to change the icon of the custom social media with a double-click => The icon cannot be changed. Note that [another commit] had already been made and fixed the problem halfway (the icon change didn't work on double-click). This commit reverts it and fixes the problem correctly with the new system.
